10 Best Free SEO Tools

Whether you are running an online business for yourself or managing digital marketing for someone else, there are essentially two options when it comes to SEO tools: free and paid. If you are willing to pay for the premium versions of many of these tools, you might want to also consider completely outsourcing this function altogether.

If you want to take the budget-friendly option, and particularly if you are just starting, you likely want to consider many of the great free options out there. With that in mind, below are some of the best free SEO tools available to anyone trying to get their site’s digital marketing off the ground.

Google Keyword Planner


If you want to increase your site’s organic traffic, then you absolutely must use a keyword planner. Google’s Keyword Planner has been the benchmark for a long time and it is free. The kicker, however, is that you need to already have a Google Ads account, which fortunately is something you can sign up for in a matter of minutes. Following your account creation, you log in. Then click the wrench icon at the top of the page and then select the keyword planner.

The keyword planner allows you to filter and sort your keyword results, analyze and select keywords from the keyword ideas section, and see the precise keyword search volume data so that you are making highly informed decisions about the keywords you choose to target. Randomly and haphazardly going after keywords without understanding the numbers behind them and their likelihood of success in the SERPs is going to be a waste of your time and money.


In the time of discussing the searcher intent as Jason McMahon, the Director of Strategy at Bambrick, nicely elaborated the following in one of his recent blog posts,

“Google’s Keyword Planner is the most popular keyword research tool — paid or free — on the market. While Keyword Planner provides a wealth of metrics, including average monthly search volume, suggested PPC bids, and competition levels, it isn’t helpful in determining what people are actually looking for when they enter a search term into Google’s search engine.”

Google’s Mobile Analysis Tool


Your site’s responsiveness (i.e., how well it displays across devices and browsers) is of paramount importance for SEO. If a visitor arrives at your site using a mobile browser, but you haven’t optimized things to display well on a phone screen, that visitor will sooner leave your site than endure the pain of trying to navigate something tedious, hard to read, and that displays poorly. More than half of web traffic is mobile now, and you fail to cater to that at your peril.


Google’s mobile-friendly test is invaluable because it ensures your site is tailored to what Google refers to as its “mobile-first indexing.” You don’t need to pay a full-time web developer to ensure your site is mobile-friendly. Most new themes on places like WordPress or Squarespace are already mobile-optimized, but even then, you should always run your site through mobile-friendly tests.

Remember, it is not only about your off-page SEO (your content and links). If you want to stand even the slightest chance of rising to the top of the SERPs you need to be meticulous about your on-page SEO as well. Not only that, but you need to be ruthless when it comes to weeding out and fixing your SEO shortcomings. This means holding a mirror up to your site and not looking away. SEObility is a free tool that helps you do precisely that.

It will crawl your site and let you know about all of your on-page SEO flaws, including your slow-loading pages, blocked pages, sitemap issues, a wide range of technical SEO problems, and much more. This is the kind of insight you tend to only get from paid SEO tools–of which there are certainly a lot of good ones to choose from. Pay special attention to the tool’s “content report” which tells you when it has found what it considers keyword stuffing, thin content, and duplicate content.

Keyworddit: Reddit Keyword Research Tool

Reddit has become a powerful tool for SEO and an important part of SEO strategy for companies and individuals. It is both a place to do keyword research as well as market (tactfully) your website’s content and manage your brand mentions and image.

Ahrefs is one of the most powerful and, depending on the plan you purchase, the most expensive SEO tools out there.

By far its most highly regarded features are its backlink tools, and the free backlink checker is a great way to get an understanding of your competitors’ SEO backlink profiles.


The free tool limits you to 100 links, but if you are just starting, then knowing where your high-ranking competitors are getting their top links from can help you build a similar profile and hopefully start moving up the SERPs. As your site progresses and your budget for SEO tools grows along with it. Then you might want to consider upgrading from a free to a paid version with more capabilities and power.
