The Best Free SEO Tools Every Marketer Should Use
SEO is one of the most effective ways to drive long-term, high-quality traffic to your website. But not every business has the budget for expensive premium tools. The good news is that many free SEO tools are powerful enough to support keyword research, technical optimisation and performance tracking when used correctly.
Below are some of the best free SEO tools every marketer should be using.
1. Google Search Console
Google Search Console is essential for any website owner. It shows how your site performs in Google search and highlights issues that may be holding rankings back.
You can track keyword impressions and clicks, submit sitemaps, identify indexing issues and monitor mobile usability. It’s one of the most important tools for understanding how Google views your website.
2. Google Analytics
Google Analytics provides valuable insight into how users interact with your site. It allows marketers to see where traffic comes from, how users behave on pages and which content drives conversions.
When paired with Search Console, it gives a clear picture of how SEO performance translates into real business results.
3. Ubersuggest
Ubersuggest is a popular free tool for keyword research and competitor analysis. It helps marketers discover keyword ideas, search volumes and competition levels, making it easier to identify opportunities for content creation.
It also provides basic site audits and insights into competitors’ top-performing pages.
4. Ahrefs Free SEO Tools
While Ahrefs is known as a premium platform, its free tools are still extremely useful. These include a backlink checker, keyword generator and website authority checker.
For marketers focused on link building and competitor research, Ahrefs’ free tools are a strong starting point.
5. SEMrush (Free Version)
SEMrush’s free account gives limited access to keyword research, backlink data and site audits. While usage is capped, it’s still useful for spot checks, competitor analysis and identifying SEO issues.
6. MozBar
MozBar is a free browser extension that displays key SEO metrics as you browse the web. It allows you to check domain authority, page authority and on-page SEO elements instantly.
This is particularly useful for competitor research and evaluating link opportunities.
7. AnswerThePublic
AnswerThePublic helps uncover the questions people are actually searching for online. It’s ideal for content planning, blog ideas and targeting long-tail keywords that match search intent.
8. Screaming Frog SEO Spider (Free Version)
Screaming Frog’s free version allows you to crawl up to 500 URLs, helping identify broken links, duplicate content and missing metadata. It’s one of the best tools for technical SEO audits.
9. Keyword Surfer
Keyword Surfer is a free Chrome extension that shows keyword search volume directly in Google search results. It’s quick, simple and ideal for fast keyword validation.
10. Yoast SEO (WordPress Users)
Yoast SEO remains one of the best free plugins for on-page optimisation. It helps manage metadata, readability, sitemaps and canonical URLs, all essential for SEO success.
