If you are searching for the best SEO plugins for WordPress sites, your search ends here. I have been using many top class SEO plugins on my WordPress sites to increase my search engine rankings. In this detailed guide, I’m going to share you the top plugins for improving your search engine traffic.

Search engine optimization is the ONLY way to boost your organic traffic results and also your ranking factors. Without SEO, you can’t build a profitable online business in 2021 and beyond.

But most bloggers find it very difficult to get good results from the search engines mainly because they are not at all aware of how to optimize their posts and pages. Luckily, if you are a WordPress user, there are tons of great SEO plugins out there, majority of them are free and I’m going to share all of them in this detailed SEO guide.

Before going into the details, I want to discuss few essential things with you.

Do SEO plugins help you improve rankings?

Yes, definitely few plugins for WordPress will help you get better search rankings for your web pages and posts. Moreover you don’t have to be a SEO master to get more traffic from search engines. All you need to know is how to use the plugins the right way. By using the right combination of plugins and tools, you will be amazed with the search engine traffic that you get.

Should you use FREE or Premium SEO plugins?

It depends on your website needs. If you are trying to get millions of page views each month, you should definitely be using premium SEO plugins to get more search traffic. But if you are new to SEO and don’t want to give much priority to search traffic, then free SEO plugins can work. Mind that, there are lots of free SEO plugins out there that are worth paying for.

    These tips and tricks are really amazing, I hope these tips will help me for my first wordpress blog.
    Really thanks a lot.

  12. Anil Agarwal says:

    For showing related posts, you can use Related post plugin or nrelate. I’m currently using nrelate plugin for showing related posts at the end of a post on my blog. This way I’m able to interlink my content contents. Apart from this, in the past, I used to use smart seo links plugin, but these days if you go by Google algorithms, you should not use that plugin. If you don’t use that plugin intelligently, you may end up building too many backlinks using the same anchor text.

    So within post, I used to do interlinking manually.

    • Abhijit Bangal says:

      Actually, I am also using smart seo links on both of my sites – Gadget Garrio and ZeroDollarBlog. What do you suggest, should I keep them or do manual linking? Actually when I didn’t know of that plugin, I used to link manually. I need your suggestion, that will be really great.

      • Anil Agarwal says:

        I would suggest you start doing internal linking manually because though seo smart link plugin, you may end up building too many back links using the same anchor text.

  13. vino says:

    Many thanks for these useful plugins. Definetely wordpress has the big advantage as it have many plugins to simplify our work. The Plugins you have listed here are worth to try.I already have tried few plugins listed here.For internal linking which is better? doing it ourself or using a plugin.What do you suggest out of experience?

  14. Anil Agarwal says:

    Abhijit I’m currently using some of these plugins on my blog. One is used for caching purpose, one for on page seo and another one for fixing technical seo issues. Apart from this, I used to activate the broken link checker plugin to fix the broken link issues on my blog.

    And if you ask me the total plugins that I’m using on my blog, the number will be 18-20.

    Some other important plugins would recommend using will be:

    – for showing the related post
    – for social media integration
    – for interacting email subscription boxes
    – for image compression

    • Abhijit Bangal says:

      First of all, sorry for the late reply to your reply as you have mentioned so many beautiful things here.
      I am surprised to hear that you are using more than one plugin only for SEO. I am actually currently using only Yoast and I thought that would be enough. But yes, I am using one for related content as well. I haven’t found any for email subscription boxes. I have taken one from Feedburner. But it looks very dull as it’s not in a box. Can you suggest any like you use?

      • Anil Agarwal says:

        Abhijit I’m currently using two plugins for showing email subscription forms at different levels on my blog. First one is from maxblogpress and another one is from get response. I would suggest you to give a try to maxlogpress plugin which is a premium plugin and will help you show cool subscription forms and light box at different levels on your blog.

  15. Abhijit Bangal says:

    This article has created a bit of a confusion for me in terms of the plugins mentioned. And I see this as a good sign that there are so many things to choose from. But I am currently using one of these plugins and I hope that will be useful.
