Whenever I dream up a home improvement project for my place, I end up working smartest and fastest when I have the right tools at my disposal. It’s amazing the difference a good tool can make – and the extra time it takes to get work done without a helpful tool.
Fast-forward to online marketing. How can you work smarter and faster with SEO?
It starts with having the right tools.
I’ve collected a big sampling of the best free SEO tools on the market—tools with various uses covering several common needs. 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.
Check the speed and usability of your site on multiple devices
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 on a score from 0 - 100. It tells you exactly how fast it takes to load the site according to different metrics and also suggests areas for improvement.
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 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.
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.
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).”
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.
Comprehensive link analysis
Limitations: Free for the top 100 backlinks
The free version of Ahrefs’ Backlink Checker shows the top 100 backlinks to any website or URL, along with the total number of backlinks and referring domains (links from unique sites), Domain Rating (DR), and URL Rating (UR) where applicable.
A great way to use this tool is to paste your competitor’s website and find potential link-building opportunities.
Alternatives: Moz Link Explorer
Know what people search for
Limitations: You’ll need to run an ad campaign to see exact search volumes
Enter a keyword or group of keywords into the tool, and Google Keyword Planner will return all sorts of helpful stats to guide your keyword strategy: monthly search volume, competition, and even suggested terms you might not have considered.
Alternatives: Bing Keyword Planner

See the relative search popularity of topics
Google Trends shows the popular search terms over time, which is useful for uncovering seasonal variations in search popularity. Compare multiple terms to see their relative popularity over time.
Check the broken links, redirect chains, nofollow links, and on-page elements for any webpage
Limitations: Technical and on-page SEO features are free, but you’ll need an Ahrefs account to see SEO metrics within the SERPs
The Ahrefs SEO toolbar is a free Chrome and Firefox extension that allows you to check for broken links, trace redirect chains, and highlight no-follow links for any webpage. It also generates an on-page SEO report that includes the web page's:
- Meta description
- Word count

- OG tags
This makes analyzing any page much easier and faster.
If you have access to a paid Ahrefs account, you’ll also be able to see important keyword metrics like search volume, CPC, and keyword difficulty within the SERPs.
See how your local business looks online
Limitations: Data is only available for three countries: US, Canada & UK

Customize how your web pages appear in the search results
Create custom code so that your reviews, events, organizations, and people are displayed the way you want in Google’s search results. Once you’ve created your schema code, copy and paste into your website.
Then, use the next tool to check if the implementation has been done correctly.
Alternatives: Merkle’s Schema Markup Generator
Check if your structured data was implemented correctly
Always double-check to make sure you’re implementing the technical aspects of SEO right. Use this tool to see if your structured data/schema markup was done correctly.
View site stats for any domain
Limitations: You’ll need a paid account to see every data point, but the free version is good enough to get a snapshot of your competitor’s activity
Use this tool to estimate how much traffic a website gets. See a breakdown of traffic sources, locations, and more. A helpful tool for competitor research.
16. SERP Robot
See your ranking position for up to five keywords
Enter any website or web page and up to five keywords to see where you rank for each of them. Check your competitors’ rankings too.
17. XML Sitemaps
Create a sitemap
Limitations: Free up to 500 pages
Simply enter your site’s URL and some optional parameters, and XML Sitemaps will create a sitemap that you can upload to Google Search Console and Bing Webmaster Tools.
Generate a robots.txt for your site
Robots.txt files let web robots know what to do with a website’s pages. When a page is disallowed in robots.txt, that represents instructions telling the robots to completely skip over those web pages.

Check for duplicate content
Limitations: Only the top 10 results are shown

22. Exploding Topics
Discover the hottest trends
SEOs often target topics with high search volume, but that means targeting topics that are already popular. What if you could find and target topics right before they hit the mainstream?
Use this tool to do that.
Generate hreflang tags for your multi-language/multi-country site
If your site targets different countries or different languages, you’ll need to set up your hreflang tags properly. Unfortunately, it’s quite easy to mess up, which can cause issues for your site.
Enter your site’s URL, the language and country of the URL, and the tool will generate the necessary hreflang annotations for you.
24. Keyword Surfer
See search volumes and CPC data within the SERPs
Install this free Chrome extension and you’ll be able to see search volumes and CPC data for any keyword you enter into Google. You’ll also see suggested keyword ideas that are related to your query.
