What Are SERP Features? From Featured Snippets to AI Overviews and Their Effect on Rankings

The SERP (Search Engine Results Page) is the page you land on after a search. It used to be ten blue links. Today the same page holds a map, question boxes, images, videos, product cards and AI-generated summaries. These blocks are called SERP features, and each one changes the place, the size and the clicks of the organic results.

Being second for a keyword means very different things depending on the layout of the page. With no blocks above, second place sits at the top of the screen. With an AI overview, a featured snippet and a four-question box above it, the same second place sits a full screen lower. Understanding SERP features is therefore an inseparable part of rank tracking.

The most common SERP features

Featured snippet

A box at the very top of the results that shows a short answer to a question together with a link to the source. It can be a paragraph, a list or a table. It is very common for informational queries like 'how to make sourdough starter'. For the source site it brings big visibility; but if the box gives the complete answer, the user may leave without clicking.

There is no guaranteed way to win the snippet, but it is known to be picked from pages already on page one. A clear two- or three-sentence answer right under the question, a numbered list for step-by-step tasks and a table for comparisons improve your odds. Keep watching after you win it; Google changes the source often, and when you lose it your clicks can fall in a day even though your position stays the same.

People also ask

A block listing related questions as expandable boxes; each one opens to show a short answer and its source. The list grows as the user opens boxes. Because it shows the sub-questions around the query, this block is valuable for content planning too. For a Brooklyn bakery, 'how long does sourdough bread keep' and 'why is sourdough sour' come out of here, and each can become a subheading.

Local pack

A block made of a map and three business cards under it. It appears at the top for queries with local intent, especially on mobile. The cards are fed directly by the Google Business Profile; so even if your web page is first in the organic results, if you are not on the map you are not on the first screen for that query. We explained how to get onto the map in the local SEO guide.

Images and videos

The image pack is a horizontal strip of images common in product and design queries; for searches like 'white sneakers outfit' it sits above or in the middle of the results. The video carousel appears for 'how to' queries and mostly consists of YouTube content. Both blocks take up a lot of vertical space; the organic results beneath them move a screen lower.

Shopping results

A block of product cards that can appear for commercial queries as ads and as free listings. It carries a price, an image and the seller's name. For an online shoe store this block is a visibility channel independent of organic ranking; it requires sending product data through Merchant Center.

Sitelinks, knowledge panel, news

For brand queries, extra links appear under the main result; for well-known people and organizations, a knowledge panel appears on the right or at the top; for current topics, a news carousel. These belong to specific query types and do not have to be every site's target.

AI Overview

An AI-generated summary block that Google shows at the top of the results for some queries. It contains an answer compiled from several sources and links to those sources. Which queries trigger it is not fixed; Google changes this constantly. Because its look and scope keep changing, firm rules are hard to set, but two things are clear: the block takes a lot of space, and some users find the answer in the summary and do not click. Being shown as a source inside the summary is a new kind of visibility. How often your brand is mentioned in these summaries and in AI assistants deserves to be treated as a separate question; AI brand visibility measures exactly that.

How SERP features affect rankings

Technically, SERP features do not change your organic ranking; the first organic result is still the first organic result. What changes is the value of that position. The effect shows up in three ways:

• Position holds, clicks fall. Every block added above pushes the organic results down. This is the most common cause of the complaint 'my ranking did not change but my traffic dropped'.
• Zero-click searches rise. For queries like weather, translations, short definitions and simple calculations, the user sees the answer on the page. Being first for these keywords brings less traffic than you would think.
• New doors to visibility open. The snippet, the question boxes, the image pack and the source links in the AI summary can put you on the first screen regardless of your organic position. A page that is sixth organically moves to the top if it wins the snippet.

Take the keyword 'white sneakers' for an online shoe store. You are second organically; but the top of the page holds shopping cards, below them an image pack, below that a few question boxes. Organic second place is the third or fourth screen the user sees. The same site's 'how to clean sneakers' post is only fifth organically but appears on the first screen because it won the featured snippet. In the position table the first keyword looks better; the real traffic comes from the second.

This is why measuring a keyword's value by search volume alone misleads. A keyword with high volume but a first screen full of blocks can bring fewer visitors than a keyword with low volume and a clean results page. Make it a habit to look at the layout of the results page when doing keyword research.

Tracking the layout of the results page

SERP features change over time. Google adds a question box to a keyword this month and removes it next month; the image pack moves down, an AI summary appears. Without watching these moves, you cannot explain changes in clicks. A good tracking setup records two more things next to the position: which blocks are on the page, and which of those blocks you appear in.

Ask three questions when reading this data. Which blocks are always there, which come and go, and which ones am I in? The permanent ones define the real first screen for that keyword; the ones that come and go create volatility; the ones you appear in are your gains independent of organic position.

In weranklab every check records the special blocks on the results page and your site's presence in them; the visibility metric takes the effect of these blocks into account along with the position. So when your position holds but your visibility falls for a keyword, you see why right on the chart. For the basics of a tracking setup, see the rank tracking guide.

Open the results pages for your target keywords yourself once a quarter. Tools tell you that a block exists; how it looks, what it promises and why a user would or would not click, you only understand with your own eyes.

Which feature should you target?

Not every block is reachable for every site; a recipe site and a software site can get into different blocks. A realistic priority order for your own keywords might look like this:

1. Question boxes and the featured snippet: reachable for every site that produces content. Start by adding clear questions and short answers to your existing posts.
2. Local pack: the first priority if you have a physical address or a service area. There is no way in without a Business Profile.
3. Image pack: possible for product, design, food and venue content with photos you took yourself, carrying descriptive file names and alt text.
4. Video carousel: for how-to content, a short YouTube video often finds a place more easily than a long article.
5. Shopping: if you sell products, setting up a Merchant Center feed is a gain independent of organic effort.
6. AI summary sources: cannot be targeted directly; but clear, sourced, experience-based content raises the odds of being cited in these summaries.

If you wonder which blocks appear for your keywords, searching the keyword on Google and scrolling down the page is the most honest start. To see how your title and description hold up among those blocks, use the SERP simulator and, if needed, make your title easier to pick out on the results page.
