What are the Best SEO Tools

SEO Tools are the only way you are going to rank on Google. You can’t do it alone.

We all know that the best way to get high quality traffic that converts is through organic search. People search things all the time, in fact you probably searched up something to have landed on this article right now.

According to a study, google alone processes about 2 Trillion searches a year. Search engines (Google, Bing, etc.) then have to prioritize each and every website that is shown to the people that search for something. This is called SEO. I won’t get into the details of SEO right now, but at its very base, SEO (search engine optimization) is a way a website can optimize itself to be more appealing to Google and be ranked higher. You can see this post by Brian Dean to learn more.

Google themselves confirm that they make about about 6 changes to their algorithm a day. That’s almost 2000 updates a year! Your site will be affected by all of them, so to keep your site ranking, you need to constantly tweak your site. That’s why large corporations have full-sized teams working on SEO.

But we are not all large corporations with billions of dollars to spend! Even we at Kabducation don’t have the budget for that. Luckily, many companies have come through and provided us with free or reasonably priced SEO Tools. Before we dive in to our list of the best SEO tools in 2021, let’s get one thing out of the way.

What are the SEO Tools?

SEO tools are certain tools that help you analyse your site, find mistakes in your SEO, track your rankings and help your pages do well on google. But it doesn’t just end there. Most SEO tools help in other ways too, like tracking backlinks, domain authority, tack your competitors, measure your load times and so much more. These tools are pretty much your mentors to fix everything you do on your site.

But….. there is a catch. Even though these are made by professionals, a lot of the time at a ridiculously low price, these tools are based on algorithms and will ask you to fix some things that are not meant to be fixed. For example, Kabducation’s Subscribe Now page has a low word count, but a subscribe now page does not need to be a large thesis, however, the SEO tool doesn’t know this. So keep that in mind when you use these tools.

But now, for the moment you’ve all been waiting for, the Best SEO Tools in 2021, here are our favourites:

Conclusion “What are the Best SEO Tools”

To conclude, Ubersuggest is an all-round champion. SEMRush is great for PPC campaigns and link building, but the SEO Audit is a bit inaccurate. Ahrefs is close, but loses some points in link building. On the other hand, Moz is great, but very Domain Authority focused and pretty expensive for beginners. Yoast SEO is amazing for optimizing specific posts and pages on your site too but doesn’t provide off-page SEO tools.

So what’s the verdict? Well, it’s complicated. No one tool can help your website grow. You have to use a combination of all these tools to get your site to the top. The great part is that a lot of the time, these tools funnel you towards using their specialities.

Ubersuggest for SEO audit, SEMRush for social media, backlinks and rank tracking, Ahrefs for keyword research and a general report, Moz for Domain authority tracking, and Yoast SEO for optimization of specific posts and pages.
