What is a SERP and How Does It Work?
A SERP is the page Google shows after a search. Here is what it contains, how different result types affect click-through rates, and how to preview yours.

A SERP is a search engine results page: the page Google, Bing, or any other search engine displays in response to a query. Every time someone types a search and hits enter, they see a SERP. What appears on that page, and in what order, is determined by each search engine's ranking algorithm.
Understanding what a SERP contains and how your result appears within it is fundamental to SEO. Ranking in position one means nothing if your title and description do not convince users to click.
What does a SERP contain?
Modern SERPs are not a simple list of ten blue links. Google in particular displays a wide variety of result formats depending on the query:
Organic results
The standard ranked listings: title, URL, and meta description. These are determined by Google's ranking algorithm. Organic results are what traditional SEO targets.
Paid results (Google Ads)
Ads appear above and sometimes below organic results. They are labelled "Sponsored". Paid results do not affect organic rankings and vice versa.
Featured snippet
A box at the top of organic results that pulls a direct answer from a highly-ranked page. Featured snippets display a paragraph, list, or table from the page, plus the URL. Appearing in the featured snippet means appearing at position zero: above the first organic result.
AI Overview (formerly SGE)
Google's AI-generated summary appears at the top of results for many queries, pulling from multiple pages and citing sources. Pages cited in AI Overviews receive a significant visibility boost. See what is Generative Engine Optimisation for how to optimise for this format.
People Also Ask
An expandable box containing related questions. Each question expands to show a brief answer pulled from a relevant page. Appearing in People Also Ask generates visibility and branded impressions even without a direct click.
Knowledge Panel
A sidebar panel for branded searches, organisations, people, places, and products. Pulled from Google's Knowledge Graph, often informed by Wikipedia, official websites, and structured data.
Local Pack
For queries with local intent ("plumber near me", "coffee shop London"), Google displays a map and three local business listings. Local Pack results are driven by Google Business Profile data, not standard organic SEO.
Image pack, video results, news
Visual and media results displayed when Google determines the query has image, video, or news intent.
Shopping results
Product listings with images, prices, and merchant names. Driven by Google Merchant Center and Google Shopping.
Why SERP layout matters for SEO
Your organic position is only part of the picture. A result at position one surrounded by AI Overviews, featured snippets, ads, and a People Also Ask box will receive far fewer clicks than a position-one result on a clean page.
This is why click-through rate analysis matters alongside ranking position. If your page ranks first but your CTR is 3% when the average for position one is 30%, the SERP layout or your result's appearance is the problem.
The elements you can control:
- Title tag: the clickable headline in the result
- Meta description: the descriptive text beneath the title
- Schema markup: can unlock rich results (star ratings, FAQs, how-to steps) that make your result more prominent
- URL structure: a clean, readable URL builds trust and reinforces the topic
How to preview your SERP result
Before publishing or updating a page, you should see how the title tag and meta description will appear in search results. Titles and descriptions that look reasonable in a CMS can be truncated or poorly formatted in actual search results.
Crawly's free SERP preview tool shows exactly how your page will appear in Google search results. Paste in a title and meta description and see a live preview, including character counts and truncation warnings.
What is SERP position and how is it measured?
SERP position is the ranking of your page for a specific query. Position 1 is the top organic result. Position 10 is the bottom of the first page.
Average CTR by position (approximate, varies significantly by SERP features and query type):
| Position | Average CTR |
|---|---|
| 1 | 25–35% |
| 2 | 10–15% |
| 3 | 7–10% |
| 4–5 | 4–7% |
| 6–10 | 1–4% |
| Page 2+ | Under 1% |
The steep drop-off from position one to position two is why moving from position two to position one has an outsized impact on traffic.
SERP features and their impact on CTR
SERP features change the click-through dynamics significantly:
- A featured snippet can capture 8-10% of clicks even when appearing above position one
- AI Overviews reduce clicks to organic results below them, with some studies showing 20-40% fewer clicks on queries where AI Overviews appear
- People Also Ask boxes at the top of results push organic positions further down the page
Tracking your SERP positions in tools like Google Search Console alongside actual click-through rate gives a more accurate picture than rank alone.
SERPs in 2026
SERPs have become significantly more complex over the past few years. AI features, expanded ads, and rich results mean that many queries produce pages where traditional organic results are several scrolls below the fold.
This makes result quality more important than ever. A result that appears at position one but has a weak title and no schema markup will be passed over by users scanning a SERP crowded with richer-looking results. Optimising your title, description, and structured data is more impactful now than at any point in the history of search.
