SERP analysis
Definition
SERP analysis is the systematic study of a search engine results page for a target query — the ranked links, AI Overviews, People Also Ask boxes, knowledge panels, video carousels, and ads — to understand what Google thinks the user wants and what content format is winning. In 2026, SERP analysis has expanded to include AI Mode citations and AI Overview source lists alongside the traditional ten blue links.
How SERP analysis works
A complete SERP analysis captures every surface Google renders for a target query:
-
AI Overview (when present): the synthesized summary at the top of the SERP, with its cited source list.
-
Top 10 organic results: titles, URLs, meta descriptions, and the dominant content format (definition page, listicle, comparison, tutorial).
-
People Also Ask boxes: surface adjacent questions Google associates with the query.
-
Featured snippets: the answer Google has lifted into a zero-click position.
-
Knowledge panels: entity cards that signal Google's understanding of the brand or topic.
-
Vertical results: video carousel, image pack, news, shopping, local pack — each tells you what content modality wins.
-
Ads: paid surfaces and how many advertisers are bidding (a commercial-intent signal).
Cross-checking the same query in AI Mode and Perplexity adds the AI-search dimension — typically a different set of cited sources from the organic top 10.
SERP analysis vs keyword research
Keyword research finds the queries worth pursuing. SERP analysis decides how to win them.
A keyword can have monthly search volume of 50,000 and still be impossible to rank for if the SERP is dominated by Wikipedia, brand-owned sites, and AI Overviews. SERP analysis is what tells you that — before you invest in writing.
In practice, the two are sequential: research the keyword universe, then SERP-analyze the highest- potential queries to filter out the unwinnable ones.

Why it matters
SERP analysis is the discipline that prevents writing content nobody can find. Three concrete payoffs:
-
Match the dominant content format. If the top 10 are all listicles, a deep definition page won't rank. If they're all definition pages, a listicle won't either.
-
Read AI Overview citations. The sources Google cites in an AI Overview reveal the model's authority hierarchy for the query. Earning a spot on that list is a higher-leverage win than ranking #6 organically.
-
Surface intent shifts. A query whose SERP shifts from definition pages to comparison pages signals the audience has moved from research to decision intent. Plan content updates accordingly.
How to run a SERP analysis
Five-step SERP analysis workflow:
-
Capture the SERP. Run the query in an incognito window with a defined location. Save the full page including AI Overview and People Also Ask.
-
Classify the dominant content format. Listicle, definition, comparison, tutorial, or hybrid. Note average word count and on-page structure.
-
Extract AI Overview citations. List the domains Google cites in the AI Overview. Cross- reference against the organic top 10 — overlap is typically only 30–50%.
-
Run the same query in AI Mode and Perplexity. Compare cited sources. The intersection of all three surfaces is your authority benchmark for the query.
-
Map gaps to opportunities. A site cited in AI Overviews but not ranking organically (or vice versa) usually represents a fixable on-page gap — schema, atomic openings, or freshness.
Frequently asked questions
Should I include AI Overviews in SERP analysis?
Yes — they're now the most prominent surface on eligible queries. The cited sources in an AI Overview reveal Google's authority hierarchy for the query and frequently differ from the organic top 10.
How do I capture a SERP for analysis?
Run the query in an incognito window with a defined location. Capture the full page (HTML or screenshot) including the AI Overview, People Also Ask, knowledge panel, and any vertical surfaces. Indexly automates this across queries and platforms.
Does SERP analysis still matter with AI search?
More than ever. AI Overviews and AI Mode are now part of the SERP, and the citations they pull from shape what users see before clicking. Modern SERP analysis includes AI surfaces, not just ranked links.
How often should I re-analyze a SERP?
For high-priority queries: monthly. The SERP can shift meaningfully after a Google core update, after AI Overview eligibility changes, or after competitors publish new content. Quarterly is the minimum for any tracked query.
Can I automate SERP analysis?
Yes — across queries, locations, and platforms. Tools like Indexly capture SERPs, AI Overview citations, and AI Mode responses on a recurring schedule and surface format and citation shifts automatically.
Keyword research
Keyword research is the practice of identifying the queries your audience actually types into Google, Bing, and AI assistants — with their volume, intent, difficulty, and competitive landscape — to ground content investment in real demand. In 2026, modern keyword research extends beyond head-term and long-tail keywords to include *prompts*: the conversational queries buyers send to ChatGPT, Claude, Perplexity, and AI Mode.
Keyword clustering
Keyword clustering is the practice of grouping related queries into topical clusters that map to a single page or content asset — instead of building one page per individual keyword. Clustering is what turns a 5,000-keyword research dump into a 20-cluster content roadmap and is foundational to both modern SEO and Generative Engine Optimization (GEO).
Search intent
Search intent is the underlying goal behind a query — what the user is actually trying to accomplish when they search. Classifying intent is the foundation of modern SEO and AI search optimization because the right answer for an informational query ("what is share of voice") is structurally different from the right answer for a transactional query ("buy AI visibility tracking software").
Content gap analysis
Content gap analysis is the systematic comparison of your site's content coverage against competitors and against the queries your audience actually searches — surfacing topics where competitors rank or earn AI citations and you don't. In 2026 it expands beyond Google rankings to include AI search gaps — topics where ChatGPT, Claude, Perplexity, and AI Overviews cite competitors but never mention you.
AI Overview
AI Overview is Google's AI-generated answer feature that appears at the top of search results, synthesizing information from multiple web sources into a single response with inline citations. Powered by Gemini and using query fan-out to retrieve from across the web, AI Overviews now appear on roughly 48% of US Google searches and have fundamentally restructured organic visibility.
AI Mode
AI Mode is Google Search's dedicated generative-answer surface, rolled out broadly in 2025–2026 as a tab that runs the user's query through Gemini-powered retrieval and synthesis instead of (or alongside) the traditional ranked-link SERP. It is the most consumer-visible expression of Google's transition from links to answers.
