Linking to a search engine results page, such as a Google search results page, can produce unexpected results because a search engine results page (SERP) changes rapidly and may even be personalized, leading to nonidentical content for different people or across time.

For instance, a software project may have migrated from SourceForge to GitHub, making the old SourceForge link obsolete, whereas the SERP may show the “correct” link as the top result.
