How are search results ranked, and why do they vary by person and presentation format?

Search results are not a uniform list that everyone sees in the same ranked order. On Google, for example, organic rankings involve query relevance, content quality, usability, and search context; paid ads have a separate auction mechanism. A searcher’s location, device, and search history may affect results, while sections such as images, maps, and videos change the layout. As a result, the same organic ranking does not mean everyone sees a result in the same place, nor does it guarantee the same number of clicks.

Organic results and ads cannot be understood through the same ranking framework

Semrush’s article groups the considerations for organic search into relevance, content quality, usability, and user context and settings. Whether keywords match the query is only one part of the picture; its explanation also covers content credibility, links from other relevant websites, mobile compatibility, and loading speed. This is not a formula that guarantees a particular ranking if followed.

Ads work differently. According to the article, which ads appear and where they appear are determined by Ad Rank within the auction system, with factors including bids and the quality of ads and landing pages. This cannot be reduced to “the highest bidder always ranks first,” nor should ad placement be treated as an organic ranking.

The same search term does not necessarily produce the same set of answers

Differences between users’ results are not just about search terms. Semrush notes that Google may adjust results based on location, search history, and device type. For example, people in New York and Chicago searching for “best pizza” may see different local businesses. Differences between their results do not necessarily mean either ranking is wrong.

• Different locations: Queries about nearby businesses may produce different lists.
• Different devices: Results and their presentation may differ.
• Different search histories and settings: These may affect results, but that does not establish that every difference is caused by personalization.

Result formats change how visible “first place” is

Welly’s article, dated 2022, uses image results for “cute cats,” local information for restaurants, and videos about gift wrapping to illustrate how different media can answer queries. These were examples at the time of publication, not fixed layouts guaranteed to appear in every search today.

A 2026 Search Engine Journal article also notes that sections such as ads, maps, video thumbnails, and AI summaries may change click volume even when organic rankings remain unchanged. In a forum, Colan Nielsen argues that which type of result is most valuable depends on the industry, keyword, and layout. He also explicitly states that he is unfamiliar with relevant data later than 2021, so this is a context-dependent assessment, not a universal rule about click-through rates.

Average position is not the position every searcher sees

Another 2026 analysis from Search Engine Journal cautions that averaging positions across different locations, devices, and result formats may conceal differences. When interpreting search performance, distinguish between ranking, layout, and clicks: ranking describes position, layout affects how results are seen, and a single average may not represent what actually appears on screen.
