Google often tests variations on the search engine results page locally before releasing them to all users. Today I noticed one such variation with ‘searches relating to’ appearing at the bottom of the search engine results page.
Others have reported seeing this earlier in the year, but it’s the first time I’ve come across it as a UK user.
The results are not the search suggestions that Google provides on the likes of the browser toolbar, but contain some tangents, e.g. ‘dogpile’ under a ‘search engines’ query.
I’m not signed into Google, which was my first thought, but clearly Google has records of users searching for ‘x’ who then search for ‘y’, possibly due to failing to click on a search result. This would explain why the results are found at the bottom of the page and highlight yet again the importance of being on the first page of results.
