Run a competitive SEO analysis comparing the user's site to chosen competitors across SERP overlap, content depth, backlink profiles, technical posture, and brand presence. Use this skill whenever the user wants to analyze competitors, find content gaps, identify backlink opportunities, understand why competitors outrank them, or benchmark against the rest of their category. Triggers on competitor analysis, competitive analysis, SERP analysis, content gap, backlink gap, why is X ranking, who is winning the SERP, beat my competitor, benchmark, market positioning. Also triggers when planning a content strategy and the question 'what are competitors doing' is implicit.

Compare a site to its competitors and find the gaps worth closing. Stack-agnostic. Tool-friendly but tool-optional.
When to use
Identifying which competitors to study
Finding content gaps (topics they cover, you do not)
Finding backlink gaps (sites linking to them, not you)
Understanding why a specific competitor outranks the user
Benchmarking authority, technical posture, and content depth
When NOT to use
Single-page optimization (use seo-onpage)
Initial keyword research with no competitors yet identified (use seo-keyword first to find them)
Auditing one's own existing content (use seo-content-audit)
Required inputs
The user's site
3 to 5 named competitors (or the topic area, if competitors are not yet identified)
Access to a keyword tool, a backlink tool, and any crawler
If competitors are unknown, start by listing the top 10 ranking domains for the user's top 10 priority keywords. Pick the 3 to 5 that appear most often.
Where competitor traffic estimation is the input you need (relative scale, channel mix, audience overlap), Similarweb MCP is the strongest source. Pair with Ahrefs (for backlink and keyword overlap) and Semrush (for SERP feature presence and SEO-PR overlap). Each platform gives a different cut of the same competitive landscape; using them together produces sharper signal than any one alone.
The framework: 5 angles
Competitor analysis covers five angles. Run all five for a full picture, or pick two or three for a focused investigation.
1. SERP overlap
Where do you and the competitor compete head-to-head?
For each priority keyword, who ranks in the top 10?
For each top-10 ranking, what page type wins (article, product, comparison, video)?
Are there SERP features (featured snippet, AI overview, video, image pack) one party holds and the other does not?
Which queries do competitors rank for that the user does not? (the content gap)
2. Content depth
What does their winning content look like?
Word count and structure of their top-ranking pages
Information types they include (data tables, original research, video, calculators, downloadable assets)
Update frequency on key pages (last modified date, change history)
Internal linking patterns (do their winning pages link to commercial pages?)
Topical breadth (how many related topics do they cover?)
Score each angle. Where does the user lead? Where do they trail?
Identify gaps. Specific content gaps, specific backlink gaps, specific technical gaps.
Prioritize. Which gaps are highest leverage to close? (Big traffic potential, achievable effort, strategic fit.)
Write the report. Use the template in references/competitive-audit-template.md.
Failure patterns
Picking the wrong competitors. A site that outranks you on one keyword but operates a different business is not a competitor. Pick by SERP overlap and audience overlap, not by who you think you compete with.
Treating "more content" as the takeaway. They are not winning because they have 500 articles. They are winning because of specific content + links + UX. Find the actual lever.
Copying their pages verbatim. Diminishing returns. Beat them by being more useful, not by paraphrasing them.
Ignoring brand strength. A weaker site with a stronger brand wins on branded queries you cannot touch with content alone.
Static analysis. Re-run the analysis at least annually. Competitor strategies shift.
