Top 30+ Free SEO Tools 2023 Has to Offer

The old saying “if you build it, they will come” still works in many situations. However, when building a website in the 21st century, you’ll often need to give your website a little help before anyone so much as visits. A good content strategy is crucial for every website — and an SEO strategy should always accompany it. Good content optimized for search engines helps your website rank higher on the search results pages, potentially improving your site’s visibility.

Meaning? More clients, credibility, and sales.

Unfortunately, learning search engine optimization (SEO) can be daunting and discouraging to beginners. Luckily, many SEO tools simplify the process much easier all around. Premium SEO tools often prove invaluable — but if you’re just starting out, a free SEO tool can do the trick.

We’ve compiled a list of the best free SEO tools available in 2023. These tools are widely used and provide actual SEO value while remaining absolutely free! 

Free SEO Tools in 2023

The list below contains the best free SEO software. We’ve conveniently put them in categories to help you find one specific to your needs.

Keyword Research Tools

These free SEO tools help you discover keywords people search the web for. The tools on this list often show search volume and competition as well.

1. Keyword Planner

Keyword Planner is Google’s keyword research tool. It was initially built for people who buy pay-per-click Google Ads, so you won’t get the same results as you would from another kind of tool. Nevertheless, Keyword Planner provides useful information for your SEO strategy planning. This tool uses Google’s very own data and includes useful features like filtering by country.

Be mindful of features meant for paid ad placements, such as “competition,” as this data can throw off your SEO strategy.

2. Moz Keyword Explorer

Moz Keyword Explorer is an excellent free tool with more than 500 million keywords and keyword suggestions. It also features Keyword Difficulty Score (to determine how hard it would be to rank with a certain keyword) and some CTR data.

If you have a free Moz account, you can make ten queries per month. Each query provides up to 1,000 keyword suggestions and SERP analyses.

Try it here.

3. AnswerThePublic

AnswerThePublic is a favorite because it provides a ton of information. The long-tail keyword tool is powered by the “suggested search,” which auto-completes the search bar as you type. AnswerThePublic visualizes these search questions into an image the service calls a search cloud and then organizes them into various categories, including:

  • Questions (who, what, where, when, why, how, can, which, will, etc. before a keyword)
  • Comparisons (vs, and, or, etc. after or in the keyword)
  • Prepositions (for, near, is, with, etc. after the keyword)
  • Alphabeticals
  • Related

AnswerThePublic is a fantastic way to generate questions from a keyword search. You can use it as you create and improve your content strategy, giving you article titles or headlines that have a chance of ranking on SERPs.

4. Keyword Surfer

Keyword Surfer is Surfer SEO’s keyword tool. It’s a browser extension you can install on Google Chrome. Keyword Surfer returns the keyword search volumes from Google search results.

Alternatives: WMS Everywhere is another Chrome extension that gives you cost-per-click information, keyword suggestions, and search volume information.

5. Ubersuggest

Ubersuggest is arguably one of the best free (and paid) SEO tools available today. Founder Neil Patel kept this SEO optimization tool free for everyone, then further built upon the functionalities available at zero cost.

Ubersuggest first grew in popularity with its Keyword Ideas feature, which you can use to generate various types of keywords. You can use it to find related, preposition, question, and comparison keywords.

Although it was put on the map by Keyword Ideas, Ubersuggest has far more functionality baked in nowadays. Other features like keyword overview, top pages, traffic analyzer overview, and site audit improve your SEO strategy even more. 

Ubersuggest is one of the only SEO tools available that offers one-time purchase lifetime licenses. Their monthly paid plans are also more affordable compared to other similar tools.

Search Console is another one of Google’s tools that use Google’s data. As a result, Search Console is now one of the most useful and most reliable tools for info on how the tech giant crawls and ranks websites, including yours.

Because Search Console limits your downloads to one thousand rows of data, you might need more support. Luckily, you can use another free tool, Google Search Console Data Exporter, to download as many as 25,000 rows of data at a time.

Try it here.

8. Bing Webmaster Tools

Bing, Microsoft’s alternative to Google, doesn’t get as much traffic. With only a 2.47% share of the search engine market worldwide, you might feel ranking on Bing isn’t as significant as ranking on Google. Although Google has the lion’s share, people still use Bing, so ranking there could benefit your business. 

Try it here.

Want to also rank up on Yandex’s search engine? Try Yandex.Webmaster.

9. MozCast

MozCast is another Moz feature that helps you keep track of the Google algorithms’ behavior. It tracks daily patterns of Google’s algorithm, showing you minor changes that don’t get much (if any) press coverage. It shows the patterns over the previous day or the past 90 days. The stormier or hotter the weather is, the more the rankings on Google have changed. In comparison, an uneventful algorithm day sits at around 70°F.

Alternative: Algoroo

10. Keyword Hero

Sometimes, Google Analytics data gets returned as [not provided]. When this happens, it can really get in the way of your planning and strategizing. Keyword Hero helps solve this problem by returning the lost keyword, so you can get rid of that ‘not provided’ metric everyone hates. You can use this tool for free for as many as two thousand sessions per month.

Try it here.

16. Google Disavow Tool

Disavow helps you fight negative SEO, such as links from websites that may be seen as “spammy” or worse. Most websites don’t really need the disavow tool, which is why Google makes it hard to find. You likely won’t have spammy backlinks unless you were previously the victim of a spam attack or if you once purchased backlinks. If you’re working with a fresh website and a brand new domain, you likely won’t need to use Disavow at all.

If you choose to use the Disavow tool, remember that you cannot reverse a disavow. So before you do any disavows, do your due diligence and research whether a backlink is truly from a spammy website. Otherwise, you could be removing backlinks that are actually beneficial to you.

Try it here.
