    Doesn’t anyone use Yoast anymore? I get reports from Ahrefs and others for years now. I often get overwhelmed looking at it all and don’t know how to fix half the things it reports anyway. I’ve also used Diib and get reports from them also. Paid for the premium version once for a few months but still couldn’t really see much value especially when I don’t know what errors are normal and to be expected on an old site and what things I should focus on. For example I spent ages erasing what I figured were bad backlinks and disavowed them, went through a long list night after night. Spent hours on it and then after a few months my website was dropping in the SERPs and ended up ranking worse it has in 20 years. Probably did more damage than good. I won’t do that again.

    • WPBeginner Support says

      People still do use the Yoast plugin, we mainly prefer AIOSEO as an alternative for a beginner friendly option. Should you decide to try a content optimization tool again and hopefully one from our list we would recommend checking for any documentation from the tool itself as normally they elaborate on what the specific errors mean and what should be done about them.

      You can also reach out to the support for these tools for help understanding what each error means including specific errors that you are unsure how to proceed with.


  3. Moinuddin Waheed says

    These tools are so expensive for beginners bloggers and a beginner blogger can’t make a big decision for making a purchase of these.
    However, AIOSEO is affordable and even it’s free plan has many things at its end.
    one can get started with this and as time passes and one gets expertise can upgrade and can even move to more options to explore.

    • Dennis Muthomi says

      Yeah that’s the good thing about AIOSEO. For me I use it along side Surfer SEO which is a bit more expensive but it is worth it.
      I like to use more than one tool when it comes to SEO stuff so that I can get to compare data and make adjustments when needed.

      • uzoma ichetaonye says

        To me, i will prefer using one paid tool and the free one which is the headline analyzer. I am sure it will help me get a more accurate results as compared to one and it is a bit more economical.
        But if one is financially buoyant enough to afford 2 or more paid tools, then that is good on its own. Good luck to you.
