SEO Tools

SEO tools are software and services that help you research keywords, audit websites, track rankings, analyse backlinks and measure performance. The right tools save time and reveal insights, but no tool replaces judgement: they collect data, and you decide what it means.

Free tools from Google and Bing

Google Search Console: performance, indexing, Core Web Vitals, links and manual actions, using Google’s own data. Essential for every site.
Google Analytics 4: what visitors do after they arrive, including conversions.
PageSpeed Insights and Lighthouse: speed and Core Web Vitals testing.
Rich Results Test: structured data validation.
Google Business Profile: local listing management and insights.
Google Trends: changes in search interest over time.
Google Keyword Planner: keyword ideas and search volume ranges.
Bing Webmaster Tools: Bing’s equivalent of Search Console, with useful extra reports.

Website crawlers

Crawlers such as Screaming Frog SEO Spider and Sitebulb scan your site like a search engine, finding broken links, redirects, duplicate titles, missing tags, orphan pages and much more. They are central to any SEO Audit.

All-in-one SEO platforms

Tools such as Semrush, Ahrefs, Moz and SE Ranking combine:

Keyword research with volume and difficulty estimates.
Competitor analysis.
Backlink databases.
Site audits.
Rank tracking.
Content and AI visibility features.

Each has different strengths and databases, so data varies between them.

Specialist tools

Local SEO tools for citation management and grid-based map rank tracking.
Content optimisation tools that compare your content with ranking pages.
Log file analysers for crawl analysis on large sites (Log File Analysis).
AI visibility trackers that monitor citations in AI answers.
Browser extensions for quick on-page checks, headings, structured data and redirects.

AI tools

AI assistants can speed up research, outlines, schema writing, data analysis and brainstorming. Use them as assistants: check facts, add your own expertise and never publish unreviewed output at scale (Helpful Content).

How to choose SEO tools

Start with the free Google tools; many small businesses need little else at first.
Add a crawler for technical checks.
Choose one all-in-one platform if you need keyword, competitor and backlink data regularly.
Consider data coverage for your market, such as UK keyword data and local tracking.
Avoid paying for overlapping tools.
Use trials to compare before committing.

Using tools wisely

Treat third-party metrics as estimates, not facts.
Do not chase tool scores, such as site health percentages or Domain Authority, for their own sake.
Prioritise issues by real impact, not by the number of warnings.
Combine data from several sources before drawing conclusions.

Tools make good SEO faster, but experience is what turns their data into the right decisions. If you would like to learn more about building those skills, read how to become an SEO expert.
