It starts with having the right tools.

Here are the best free SEO tools on the market that will fill up your toolkit with options for every scenario. Whether you're a pro or not, these tools are fast, free, and easy to use. I hope you find one or two (or twenty) you can put to good use today.

At a glance: The best free SEO tools

1. Google PageSpeed Insights

Check the speed and usability of your site on multiple devices

Limitations: None

Enter a URL, and this tool will test the loading time and performance for that URL on desktop and mobile. It then grades your site’s performance from 0 – 100. It tells you exactly how fast it takes to load the site according to different metrics and suggests areas for improvement.

Alternatives: Pingdom, WebPageTest, and GTMetrix

2. Ahrefs Webmaster Tools

Run a technical audit of your site

Limitations: 10,000 crawl credits per project per month

Sign up for Ahrefs Webmaster Tools, verify your website, and you can audit your website for over 100+ technical SEO issues. The tool also gives suggestions on how to fix them.

After running an SEO audit, it also suggests areas where you can improve your internal linking, which helps boost your rankings in search engines.

This tool also lets you see your site’s organic keyword rankings and who’s linking to you.

Alternatives: Screaming Frog (audit), Beam Us Up (audit)

3. Answer the Public

Hundreds of keyword ideas based on a single keyword

Limitations: Three free searches per day; you have to sign up to use them.

Enter any relevant keyword, and Answer the Public will provide a huge list of long-tail keyword opportunities, plus common questions asked.

Alternatives: KeywordTool.io, UberSuggest, Keyword Sheeter, Keyword Generator

4. Google Analytics

Complete web stats and search insights

Limitations: No limitations for its usage, but queries that are sending you organic traffic are hidden

Quite possibly the most powerful free analytics tool available, Google Analytics tracks pretty much every bit of traffic you can imagine on your website—where it comes from, which page is receiving it and so on.

While it’s not purely for SEO, it’s still a helpful tool to track if you’re getting traffic from organic search.

However, Google Analytics has since stopped showing which keywords send you that traffic. You’ll have to pair it with a tool like Keyword Hero to uncover what’s behind “(not provided).”

Alternatives: Matomo, Open Web Analytics, and Clicky

5. Google Search Console

Constant website analysis, alerts, and error reports

Limitations: Only shows a handful of technical SEO issues, the top 1,000 backlinks, and the top 1,000 organic keywords

Google Search Console gives you a taste of what the most used search engine thinks of your website. You can use it to check and fix technical issues on your website, see important SEO data like clicks, impressions, and average ranking position, submit sitemaps, and more.

If ranking in search engines like Bing and Yandex are important to you, note that they have their own “search console” too.

Alternatives: Bing Webmaster Tools, Yandex Webmaster Tools

6. Ahrefs Backlink Checker

Comprehensive link analysis

Limitations: Free for the top 100 backlinks

A great way to use this tool is to paste your competitor’s website and find potential link-building opportunities.

Alternatives: Moz Link Explorer

7. Google Ads Keyword Planner

Know what people search for with this free keyword research tool

Limitations: You’ll need to run an ad campaign to see exact search volumes
