Deseja instalar e configurar o W3 Total Cache em seu site WordPress?
O W3 Total Cache é um popular plug-in de cache do WordPress que ajuda a melhorar a velocidade e o desempenho do seu site. Os plug-ins de cache podem ajudar a reter usuários e reduzir as taxas de rejeição, o que pode ajudar o SEO e aumentar as conversões.
Neste guia para iniciantes, mostraremos como instalar e configurar facilmente o W3 Total Cache em seu site WordPress.
Nota do editor: Não usamos mais o W3 Total Cache em nosso site e mudamos para o WP Rocket, que é um plugin de cache premium. O W3 Total Cache ainda é uma boa solução que funciona bem.
O que é o W3 Total Cache?
O W3 Total Cache é um dos melhores plug-ins de cache do WordPress que permite melhorar facilmente o desempenho e a velocidade do WordPress.
Por padrão, o WordPress usa PHP para gerar dinamicamente cada página do seu site quando ela é solicitada por um usuário.
O PHP é uma linguagem de programação do lado do servidor. Isso significa que cada solicitação do usuário aumenta a carga no seu servidor. Isso afeta o desempenho, a experiência do usuário e o SEO do seu site.
Os plug-ins de cache do WordPress ajudam a reduzir esse problema, ignorando o PHP e fornecendo uma cópia em cache da sua página da Web.
Ele também permite que você conecte facilmente seu site a uma CDN (rede de distribuição de conteúdo) para melhorar ainda mais o desempenho do site.
Instalação do W3 Total Cache no WordPress
Antes de instalar o plug-in W3 Total Cache no WordPress, é necessário certificar-se de desativar qualquer outro plug-in de cache no seu site. Isso o ajudará a economizar recursos do servidor e evitará conflitos de plugins.
Depois disso, você pode prosseguir e instalar e ativar o plug-in W3 Total Cache. Para obter mais detalhes, consulte nosso guia passo a passo sobre como instalar um plug-in do WordPress.
Após a ativação, o W3 Total Cache adicionará um novo item de menu chamado Performance à barra lateral de administração do WordPress. Ao clicar nele, será iniciado o assistente de configuração do plug-in.
Basta clicar no botão Next para continuar.
Primeiro, você será solicitado a ativar o Page Cache. Clique no botão Test Page Cache para continuar.
O W3 Total Cache mostrará a você diferentes opções de mecanismo de armazenamento. Você precisa escolher aquele que lhe poupará mais tempo. Normalmente, será a opção “Disk: Enhanced” para a maioria das plataformas de hospedagem compartilhada.
Clique no botão Next para continuar.
Agora, você terá a opção de testar o cache do banco de dados. Recomendamos escolher None (Nenhum). Para a maioria dos sites de pequeno e médio porte, o servidor MySQL poderá buscar dados mais rapidamente do que o cache do banco de dados.
Clique no botão Next para passar para a próxima etapa.
Isso o levará à seção Object Cache. O Object Caching permite que o W3 Total Cache armazene consultas ao banco de dados para páginas dinâmicas e as reutilize para melhorar o desempenho.
Se o resultado do teste mostrar uma diferença de apenas alguns milissegundos, você poderá escolher None (Nenhum).
Clique no botão seguinte para continuar.
Depois disso, clique no botão Test Browser Cache (Testar cache do navegador) e selecione a opção “Enabled” (Ativado) nos resultados do teste.
Essa opção solicita que o navegador do usuário armazene uma cópia da página da Web por um tempo limitado. Carregar uma página do cache do navegador é muito mais rápido do que carregá-la do cache do servidor da Web.
Clique no botão next para passar para a próxima etapa.
Por fim, o assistente de configuração solicitará que você ative o carregamento lento para imagens.
Agora, o WordPress vem com carregamento lento integrado para imagens. No entanto, alguns navegadores mais antigos podem não ter suporte para esse recurso.
O W3 Total Cache usa JavaScript para adicionar carregamento lento para imagens, o que pode ser ainda mais rápido e eficiente.
Depois disso, clique no botão Next (Avançar) para concluir o assistente de configuração e visualizar o painel do W3 Total Cache.
Opções avançadas de cache no W3 Total Cache
As configurações básicas funcionariam para a maioria dos sites. No entanto, há muitas opções avançadas que você pode configurar para melhorar ainda mais o desempenho.
Vamos dar uma olhada nas mais importantes.
Reduzindo JavaScript e CSS no W3 Total Cache
O termo “minify” é usado para descrever um método que reduz o tamanho dos arquivos do seu site. Ele faz isso removendo espaços em branco, linhas e caracteres desnecessários do código-fonte.
Observação: a redução dos arquivos JS e CSS pode danificar seu site. Se você ativá-la e seu site não parecer correto, basta desativar essas opções.
O W3 Total Cache também permite que você reduza facilmente o código-fonte JavaScript, CSS e HTML. Entretanto, recomendamos que você reduza apenas os arquivos JavaScript e CSS.
Basta acessar a página Performance ” Minify e rolar para baixo até a seção JS.
Marque a caixa ao lado de “JS minify settings” para ativá-la.
Agora, role para baixo até a seção CSS e ative as configurações de redução de CSS da mesma forma.
Não se esqueça de clicar no botão Save All Settings (Salvar todas as configurações) para armazenar suas configurações.
Para obter métodos alternativos, consulte nosso guia sobre como reduzir os arquivos JavaScript e CSS no WordPress.
Ativar o suporte a CDN no W3 Total Cache
As CDNs ou redes de distribuição de conteúdo ajudam a melhorar ainda mais o desempenho do seu site, fornecendo arquivos estáticos, como imagens, CSS e JavaScript, a partir de uma rede global de servidores.
Isso reduz a carga no servidor de hospedagem do WordPress e melhora a velocidade de carregamento da página.
O W3 Total Cache vem com suporte integrado para várias plataformas CDN.
Recomendamos o uso do Bunny.net, que é a melhor solução de CDN do mercado. É o que usamos em nosso site OptinMonster.
Primeiro, você precisa se registrar em uma conta Bunny.net. Após o registro, é necessário criar uma Pull Zone para o seu site.
Uma pull zone adiciona um nome de host ao Bunny.net CDN. Esse nome de host é usado para fornecer arquivos estáticos para seu site.
Adicione um nome para sua pull zone e, em seguida, forneça o nome de domínio do seu site.
Depois de adicionar a pullzone, você precisa acessar a página Desempenho ” Configurações gerais.
Em seguida, role a tela para baixo até a seção CDN.
Marque a caixa Enable (Ativar) ao lado da opção CDN e escolha Generic Mirror (Espelho genérico) ao lado da opção CDN Type (Tipo de CDN).
Não se esqueça de clicar no botão Save All Changes (Salvar todas as alterações) para armazenar suas configurações.
Em seguida, você precisa visitar a página Performance ” CDN e rolar para baixo até a seção Configuration: Objects.
Aqui, você precisa adicionar o nome de host que criou anteriormente para a pullzone e clicar no botão test mirror.
O W3 Total Cache verificará a disponibilidade de seu nome de host e exibirá a mensagem Test Passed quando for bem-sucedido.
Agora você pode clicar no botão Save All Changes (Salvar todas as alterações) para armazenar suas configurações.
O W3 Total Cache começará a fornecer seus recursos estáticos a partir do servidor CDN.
O W3 Total Cache também funciona bem com a CDN gratuita da Cloudflare. Como alternativa, você também pode usá-lo com o Sucuri, que é o melhor serviço de firewall de site com serviço de CDN integrado.
Solução de problemas com o W3 Total Cache
Depois que você configurar o W3 Total Cache corretamente, ele deverá funcionar perfeitamente em segundo plano para melhorar a velocidade do WordPress e aumentar o desempenho.
Ocasionalmente, você pode se deparar com problemas em que não vê as alterações feitas em seu site imediatamente ou um plug-in pode não estar funcionando corretamente.
O motivo mais comum para esses problemas é que você provavelmente está vendo uma versão antiga em cache do seu site.
Isso pode ser facilmente corrigido limpando o cache no WordPress.
Basta clicar no menu Performance (Desempenho) na parte superior e selecionar a opção Purge All Caches (Limpar todos os caches). O W3 Total Cache limpará todo o conteúdo armazenado em cache em seu site.
Se ainda estiver vendo a versão antiga do seu site, tente também limpar o cache do navegador.

WPBeginner Staff says
You can add your shopping cart page as an exception in w3 total cache. Under Performance > Page Cache scroll down to advanced section where you will find the option ‘Never cache the following pages’. For example, if your eCommerce plugin uses a page cart for checkout, then simply enter “cart/” to exclude that page or “cart/*” to exclude that page and all sub-pages. (Without the quotes, of course.)
Marou Wing says
Hi Guys, thank you for the awesome article, it made my site much faster than before! However I have encountered with a little issue. My site has webshop and the checkout page (due to the Credit Card payment option) has https (I have my own SSL hosted by RapidSSL). So the checkout page (I assume because of the SSL is totally messed up when the W3TotalCache is enabled, no formats, no pictures, no colours only text…) How can I fix this issue, do you have any recommendation? Thank you, Marou
WPBeginner Staff says
We haven’t noticed any significant conflicts on any of our websites where we use it. Even then, if you come across a conflict then notify the plugin author by using the support tab on the plugin’s page.
adeem jan says
Thanks for writing this tutorial on how to setup and decrease a blog load time using W3 total cache.
I use this same plugin on one of my blogs, the resulting speed of the blog is awesome.
Although, i have seen many people complain about this plugin that it sometimes conflict with other wordpress plugins.
I don’t know if you have experienced this in person?
Roger Phillips says
Hi thanks for the video I enjoyed it, I’ve used w3 total cache for over 5 years on all four of my personal sites and I honestly have to say I’ve alway had better luck 90% of the time using it right out of the box, less likely to break other function that way. Kind of the risk vrs rewards factor and that normally persuades me to just use it out of the box. After watching this video and decided to give the settings you requested a try, You helped me out quite a bit. My site went up in speed from 82% to 97% page speed, and yslow score went from 72% to 93%, thanks for the setting can’t wait to try them on my other sites!

Arif Ahmed says
I used W3 cache through my developer. My site was acting weirdly, it does not load properly on first instance and when I refresh the page it is loaded properly. This happens with every page. When I told my developer, he told me that it because my internet speed is slow and the page is not able to serve from cache. So why is this happening ? Any clue
Rachael says
Like the previous person Ss, I am new to WP and I followed this plugin tutorial video (aside from the minify, CDN stuff). I got the same message at the top of my pages in wp admin: “The setting change(s) made either invalidate the cached data or modify the behavior of the site. now to provide a consistent user experience. ” Why did this happen and Should I dismiss it or click on the empty cache button? Help, Please!
imssarl says
I installed that way, but my site design is all messed. I have my blog installed on a subdomain: blog.mydomain.com ; what should I set for the cdn? cdn.blog.mydomain.com?
Jimmy says
Yes, that’s how you do it. But I would prefer example.com/blog/ for better SEO.
Salud Casera says
I followed the instructions for beginners and all it tooks was three clicks to set it all up (if you are not using CDN). It would be good to have a more advanced version of this post.
Edit : After testing for speed, it only made my website slower.
bemed says
I mean I installed W3 Total Cache on the Network Admin but it does not show on the website that I want it to be active.
Does it handles multi-site installations or it only works individually?
bemed says
Hoe does it work on a multi site installation?

That was just what I needed. Made the setup much easier and the details allowed me to understand what the purpose of each function was. Thanks for the details!

This was extremely helpful. W3TC has some of the most non-intuitive settings I have ever seen.
Ss says
Thanks for this tut, I’m pretty new to wp and all this helps a great deal! I installed and activated this plugin as per your post (aside for the CDN part). However the following message appears at the top of all pages in wp admin: “The setting change(s) made either invalidate the cached data or modify the behavior of the site. now to provide a consistent user experience. ”
Should I dismiss this or click on the empty page cache button?
Erin Singh says
Thank you for posting this tutorial. The W3 Total Cache that I installed displays this General Setting. Does this General Setting need to be enabled as well?
Craig says
Very helpful post! Been using W3TC for quite awhile, but configuring a CDN can be a little tricky. This guide made it a breeze. Thank you!
Fauzul says
Luckily found this short tutorial, my blog page load increased severely after setting up the caches. Now I know better what to turn on and what cache to leave disabled. On shared hosting, in my opinion it’s only good to turn on page cache and browser cache.
Now going to try it with a CDN. Hopefully things can improve further.
Susan says
Hi,
I using a wp multi site install and Cloudflare but I just cannot find any instructions on how to configure W3.
When activated network wide there is nowhere to add individual distributions for each sub domain.
Or else I’m missing something!
Any help is much appreciated
cheers

You will find CloudFlare available as an extension under Performance » Extensions. After activating CloudFlare extension you will be able to see its settings.

Awesome article! Just what I was looking for – my site is on Hostgator and I’d love to use both W3 Total Cache and Max CDN. Perfect.
BUT I got lost at the point of creating subdomains. I just don’t understand what that means or how to create one. Just make one up? Find one somewhere on my site. Very confused.
My site is slow – it gets a C at best on GTMetrixs, and I’m preparing to do a big campaign. I need help.
Do ya’ll offer support services? I saw that you do free blog set ups. Would accept payment to help set these up for me?

Zubair says
Hi ! its a nice plugin . but i installed WP Fastest cache instead , so now i am facing a little problem with this . i have used contact form 7 with really simple captcha but after installing the WP Fastest Cache the captcha image is broken in the website. so how to get rid of this or if i install w3tc will i overcome this problem.
Regards
Zubair
Ashutosh Bhardwaj says
That might be the reason, because in order to make everything cachable, ur plugin might have added a query string as suffix to image name, and it broke.
Ask plugin support, they will help for sure
Philip Verghese Ariel says
Hi Admin & Syed Balkhi.
I think this looks like a bit advanced page to me, so i am going
What a pleasant land here.
I am really in search of such a page
since I am new to this platform called WP
Recently i created (migrated) my blogger page here with the help of one of my blogger friends. Now I am here via Arun’s page here at WP, and found this place is a good place for a WP beginner like me
to your Archives WPBEGINNER ARCHIVES” to find some basic lessons
Anyways I will be here to look and study around
Thanks a lot for all your efforts to put these lessons in a systematic way.
I am bookmarking this page.
Have a wonderful time.

thanks guys for your awesome job.
In the dashboard W3 gives a tip to upgrade to Pro for $99. However all the functions you described can be checked without upgrade.
Then what this upgrade is for? – should i go ahead and purchase the upgrade?
avgjoegeek says
That is for their “Pro” Service. If you use Genesis framework they will offer additional ‘special’ caching and monitoring to help speed up your site more. Most people do not need this.
Ashutosh Bhardwaj says
So u need not purchase it simple
Carla says
I’ve been trying to set up this plugin for ages. I just left the default settings and it was very helpful. Now that I have additional settings checked, my site is super speedy. Thanks so much! I did not set the CDN though because I have ClourFlare enbaled.
David Geer says
I am at the step where I configure the CDN section in W3TC. I added cdn.davidgeer.com and clicked add cname. It added it and said it was reserved for CSS. Then another field popped up to add another CNAME and it said it is reserved for js in . Should I keep adding each of my consecutive cnames to the available cname fields that pop up here in W3TC and then save settings?
WPBeginner Support says
You need to add CNAMEs you created with MAX CDN.
Administrador
Adam Lindsey says
I seem to be having an issue as well. There is the long CNAME url.url.netdna.cdn.com that works, but if I use the cdn.tnmedia.com, cdn1.tnmedia.com, etc. It doesn’t work. Isn’t it better to have JS files pulling form one subdomain and have another pulled form a different one or am I way off base here?
Joe DeCaro says
I love your site. I installed W3TC and set it up as you suggested. I’m on shared hosting. Now that it is installed, I’m getting emails from readers saying they can’t see our latest posts as they go up.
Did I do something wrong?
I set the browser cache settings step by step as you advised.
What may have cause this new issue for my readers since installing the W3?
Thanks.
My site is MetsmerizedOnline.com
Osnilton Mozarino says
Thanks for the great article!!! As usual very well written and informative.
Question: I now have a pretty clear idea about CDN, however for a regional or national only web site, will it still be benefitial to use it, as the hosting server(s) are already in the main cities, say close enough? As it seems to be a great thing for international web sites.
Thank you

Yes if u live in a big country like US. If you are in a small country then no.

Hey I have tried installing and managing with this plugin and I don’t own a cdn. do this plugin works with cdn better or we can try some extra efforts in settings to make this work better without cdn.
Should we actually use caching plugin if we are not running up with cdn services (I am involving every cache plugin)
WPBeginner Support says
W3 Total Caches works without CDN and is still very useful. However, using a CDN service will further boost your page load time.
Administrador
Zalmey says
My Question is that, will I get better performance from W3TC without MaxCDN & CloudFlare. Does anyone using it with these 2 and having a good load time?
avgjoegeek says
If setup properly? W3TC/MaxCDN and Cloudflare can significantly speed up your website.
I used W3TC to configure to use MaxCDN. Then did a manual install for CloudFlare, You don’t need to configure it within W3TC. And it is fast… very fast once it’s all setup!
Andy Crichton says
Great article. I know just about enough to get myself in trouble, so I did ask the MaxCDN guys a lot of questions before and during setup. I asked a couple of times about the subdomains, I said it sounds cool and logical to have the 4 extra to serve certain files “instantly” – they said the difference in delivery is almost non existent, like 10ms. So I havent bothered. Have you really seen a significant difference with / without the 4 subdomains at work?
thanks
PS I didnt know about your affiiation before I signed up to MaxCDN, but anyone reading, wow, the company is brilliant! There was an issue with my forum plugin – when the CDN was installed, the theme broke if you did a quote, and also members couldnt login. MaxCDN analysed it and I gave them admin access and they sorted it. Also the delivery of the site (hosted in Colorado) now in Europe is down from 4 secs to 1.5 according to pingdom.

Try turning off Database Caching, if that does not work, then you can try to optimize your WordPress database using phpMyAdmin.

I installed Total Cache several weeks ago, and since then, using my backend has been a nightmare. Every time I tried to do anything in the backend, my browser (Firefox) would hang. I finally deactivated Total Cache today, and now my backend works just ducky.

Steve says
I’ve tried several times to install caching plugins (both W3 Total Cache and WP Super Cache) and in every case, my overall site performance takes a major hit as soon as the plugin is activated/configured.
This time, I followed the instructions to the letter as shown above. However (as has occurred in every other time I’ve tried), load time throughout the site has at least tripled.
The one thing I didn’t do in every case is get a CDN, due to the cost involved.
So my question is this.. do the caching plugins only work in conjunction with a CDN?
If so, is there any other way to speed up performance (aside from the obvious – removing plugins, etc). I use WP Optimize regularly.
WPBeginner Support says
There could be some server configuration problem on your host’s end.
Administrador
Steve says
Could you give me more details on what to ask about? My hosting service service is usually good about that sort of thing, but I’d need to know specifically what to ask about.
Andrew says
Turn off database caching if you are on shared hosting, it will bring your speed back up.
Abhisek says
I am planning to go for maxCDN but, i have a dilemma that, i use a sub-domain to store all my media files something like this – media.example.com. As a result Wp-Smush it plugin no more works and i have to compress images myself using png-gauntlet software in windows. Will this sub-domain also create any problem in switching to maxCDN ?
Manasseh Copinger says
Great post really like every single post from you.
Shahraar Khan says
Very nice tutorial . But I personally like wp Super cache
Jeremy Myers says
First, where is your “after” screen shot from Pingdom? That “before” test was pretty dang good, and I am curious to see if it actually improved.
Second, I have done a lot of testing between W3 Total Cache and WP Super Cache. I agree with W3 has more options and seems to be a better plugin, but with W3, my server response time nearly tripled! It went from about .25 seconds to almost a full second. Why is this?
Third, what about Cloudflare integration? Any suggestions one way or the other?
Denise Blackman says
Hi Jeremy. I don’t have the answer to the increased response time of your server with W3, but I had the same problem. Mine, however, was even more severe, with an increase to almost 1.25 sec. I wish someone could answer this. My host provider has no answer either. My personal guess is that the server that is hosting my account, which is a shared server, is over taxed. It is normally what happens when an account suddenly has major performance issues.
In reference to CloudFlare, I have tried to integrate it, but had problems with my theme. I had to disable it. It made way too many changes to my CSS. I don’t know a lot about CloudFlare, and it sounded great. I just couldn’t figure out a way to make it work with my theme at all.
Dmitriy says
Great article, very detailed!
If someone has any questions regarding MaxCDN feel free to ask me.
Thank you
Alex says
Dmitry,
Due to localized business activity my website is set for a specific location, Moscow Russia. That said I don’t expect people from other cities to bother me. Do you think I still should go for the MaxCDN?
Thanks
Raghu says
One more step for MaxCDN : Add noindex to cdn contents to prevent Google from indexing CDN contents which will create duplicate content issues.
It’s under Zones > Pull zones > SEO
Check enable and use custom robots (with default code for robots.txt)
Alex says
Raghu,
thanks for the heads-up. Do you mean I need to edit robots.txt or there are just default options that I need to check in Zones > Pull zones > SEO section?
The necessity to touch robots.txt kind of scares me as I am not a coder.
thanks
