Shopping via Google?
Just heard (on radio) that Google is now[?] going to show paid ads for results. This means you will see large companies and those willing to pay G; not smaller companies or those unwilling to pay G - including not Amazon, who refuses to pay. Radio suggests shop local, do pre-look-ups (for price comparison or availability) via company name.
Me, I'll stick with duckduckgo, which also does not track or tag my searches.
