A SERP (Search Engine Results Page) is the entire results screen a search engine shows when a user enters a query. Today's SERP goes far beyond a simple list of links. It is filled with AI overviews, featured snippets, image packs, and more. Which position you occupy is the core of your visibility strategy.
It Is Not Just a List of Links
Today's SERP is not filled with just 10 blue links. Depending on the query, different elements are combined and displayed.
- Google AI Overviews - Summary answers generated by AI by synthesizing multiple sources. They occupy the very top of the screen and have the biggest impact on the click-through rate of organic results below.
- Featured Snippets - Excerpt answer boxes for question-type queries. They deliver such strong visibility that they are called "position zero."
- People Also Ask (PAA) - An accordion of related questions. Clicking expands the answer inside the SERP, capturing related traffic.
- Image/Video/News packs - Shown for visual or time-sensitive search intent. If your content appears as an image or YouTube video, you gain a separate entry channel.
- Local Pack (Maps) - For location-intent queries, a map and a 3-pack list of businesses appear. This is critical for store-based businesses.
- Ads (Search Ads, SA) - 1 to 4 at the top, 0 to 3 at the bottom, surrounding the organic results above and below.
Even Rank 1 Loses Clicks
As these elements take over the top of the screen, even the rank 1 link sees its actual click-through rate (CTR) drop. The CTR for organic rank 1 is commonly cited at around 30%, but when an AI overview, featured snippet, or image pack sits above it, it often falls by 10 to 20 percentage points. That is why raw rank no longer matters as much as "which SERP elements you occupy," which has become the real benchmark for SEO performance.
Mobile and Desktop SERPs Differ
Even for the same keyword, the layout changes by device.
- Mobile: Ads and the local pack often fill the entire fold, so organic results appear only after scrolling.
- Desktop: The wider screen displays the sidebar, knowledge panel, and related searches all at once.
Since 70 to 80% of Korean searches happen on mobile, you must build your occupancy strategy around the mobile SERP to win real traffic.
The GEO Era - The SERP Itself Becomes the Answer
As GEO (Generative Engine Optimization) rises, the role of the SERP is changing fast.
- Google AI Overviews/SGE: Generate answers directly at the top of the SERP. Zero-click searches, where users get the answer without clicking any link, are increasing.
- Conversational interfaces like ChatGPT, Perplexity, and Claude: Generate answers without going through a traditional SERP. Getting your content cited within those answers is the goal of GEO.
As a result, the single goal of "taking SERP rank 1" is evolving into a multi-layer KPI that tracks SERP elements + AI answer citations + direct traffic together.
How to Analyze the SERP for Your Keywords
Strategy starts with directly observing the actual SERP for your target keywords.
- Search in incognito mode on both mobile and desktop and record which SERP elements appear.
- Check the sources cited in AI overviews, featured snippets, and PAA. Those are your GEO targets.
- Verify that the search intent matches the SERP layout. If only ads appear for an informational keyword, that signals a mismatch between intent and content.
- Compare samples to see how results change by location, device, and personalization.
Notes
SERP composition varies by search intent, device (mobile/desktop), location, and personalization. The SERP for the same keyword often gains or loses elements within just a few days, so the habit of re-observing regularly is important.
