Google R&D discusses an enhancement to its related search links in an article: Fresher related search suggestions.
Let’s try to search for the animal: cat.
If you enter into Google search the keyword cat, the following links to relevant SERPs display down the page:
- Caterpillar Inc.
- Cat - Wikipedia, the free encyclopedia
- Centre for Alternative Technology Home Page
- Lolcats ‘n’ Funny Pictures of Cats
The following related search links are displayed at the top of the page:
- cat deeley
- cat stevens
- cat unix
- cat exam
Why is there such a divergence between the concept of “relevance” for SERP links and for related searches links?
If Cat Deeley, a DJ, is relevant to related searches, why doesn’t she appear as a SERP link?
If the Unix command cat is relevant to related searches, why isn’t it listed as a SERP link?
Similarly, if Caterpillar Inc. is a relevant SERP link, why isn't there a related search link to building equipment?
Relevance to a keyword/s such as cat means one thing across the top of a page, and something else down the page.
