Read guideWhy Competitor Analysis Is Central to SEO Strategy#
SEO is not played in a vacuum — you are competing for the same positions against specific other websites for every keyword you target. Understanding exactly who those competitors are, what is working for them, and where their weaknesses lie is the foundation of an efficient SEO strategy. Without competitor analysis, you are guessing at what tactics to prioritise. With it, you have a data-driven roadmap that tells you exactly what you need to do to move from your current position to theirs — and beyond.
Identifying Your True SEO Competitors#
Your SEO competitors are not necessarily your business competitors. They are the websites that currently rank for the keywords you want to rank for. A small accountancy firm in Leeds might find that its SEO competitors for the keyword "accountant Leeds" are other local accountants, a national accountancy firm's Leeds page, and an accountant directory site — none of which are direct business competitors but all of which occupy the ranking positions you need to displace.
To identify your true SEO competitors: search your 5–10 most important target keywords on Google.co.uk and note which domains appear most consistently in the top 10 results. The sites appearing across multiple high-value queries are your primary SEO competitors. Use tools like Ahrefs or SEMrush to confirm this by entering your domain into their Organic Competitors report, which automatically identifies sites ranking for the most overlapping keywords as yours.
Competitor Keyword Analysis#
1
Identify Keywords They Rank For That You Don't
Enter a competitor's domain into Ahrefs Site Explorer or SEMrush Organic Research and export their full keyword ranking list. Filter to show only keywords ranking in positions 1–20 (where most traffic is captured) and cross-reference against your own rankings. Keywords your competitors rank for that you do not are your keyword gap — proven opportunities where demand exists and ranking is achievable. Our Keyword Research guide covers how to prioritise these opportunities once identified.
2
Find Their Top-Traffic Pages
In Ahrefs or SEMrush, view your competitor's "Top Pages" report — the pages driving the most organic traffic to their site. These pages represent their most valuable SEO assets and indicate which topics and content formats are working best in your niche. Study these pages carefully: what keyword do they target? What format (guide, list, tool, comparison)? How long are they? How many backlinks do they have? This analysis tells you what to replicate and improve upon.
3
Run a Multi-Competitor Keyword Gap Analysis
SEMrush's Keyword Gap tool and Ahrefs' Content Gap feature allow you to enter multiple competitor domains simultaneously and find keywords that all (or most) of your competitors rank for that you do not. These are the most validated opportunities — if multiple competitors rank for the same term, demand is proven and your gap is clearly defined. Filter results to UK search volume data for accurate prioritisation.
Competitor Backlink Analysis#
Understanding how your competitors have built their backlink profiles reveals which link sources are most valuable in your niche and which acquisition tactics have proven effective. In Ahrefs or SEMrush, for each primary competitor: review their referring domain count vs your own (the gap to close), identify their highest-quality backlinks (sort by Domain Rating of linking page), look for patterns in link sources (specific publications, directories, or associations that link to multiple competitors in your niche), and find their most-linked-to content (this is their “linkable asset” — study it to inform your own content creation). Our Link Building guide covers how to use these insights to craft your outreach strategy.
Competitor Content Strategy Analysis#
Study your competitors' content at a structural level beyond individual pages. How frequently do they publish? What content formats do they favour (long guides, short news articles, video content, tools, comparison pages)? How do they structure their internal linking and topic clustering? How do they handle E-E-A-T signals — do they have author bylines, credentials displayed, and regular content updates? What schema markup have they implemented? These structural insights reveal the content architecture approach working in your niche and highlight specific gaps where you can differentiate and outperform. See our Content SEO guide for how to implement these insights into a full content strategy.
Technical SEO Competitive Benchmarking#
Compare your technical SEO performance against competitors using freely available tools. PageSpeed Insights allows you to compare your Core Web Vitals scores against competitor pages for the same queries. Google Search Console field data (available in the Core Web Vitals report) shows how your real-world performance compares. If your LCP is 3.5 seconds and a competitor's is 1.6 seconds for the same keyword, you have a quantified technical disadvantage that is contributing to your ranking difference. This type of benchmarking makes the business case for technical investment concrete and data-driven rather than theoretical.
Putting Competitor Analysis Into Action#
Competitor analysis is only valuable when it drives specific, prioritised action. After completing your analysis, build a competitor-informed action plan: list the top 20 keyword opportunities from your gap analysis and assign each to an existing page to optimise or a new content piece to create, identify the 5 most promising link-building sources you discovered from competitor backlink analysis and begin outreach, note the 3 most significant technical advantages competitors have over you and add these to your technical SEO roadmap. Repeat competitor analysis every quarter — both to measure your progress closing the gap and to identify new opportunities as the competitive landscape evolves.
