Google Personalized Search: End of SEO?
<a href="https://googleblog.blogspot.com/2009/12/personalized-search-for-everyone.html" target="_blank" rel="noopener noreferrer">Official Google Blog: Personalized Search for everyone</a> lot of webmasters have began complaining that all the efforts they've put in so far in SEOing their websites, will get screwed up.
What personalized search means is that there will be an anonymous cookie in your browser that will see the pattern in your clicks. The site that you click most of the times will appear on the top of search result pages. This means, if you were clicking on some other website many times, that web site will appear on the top; no matter how useful it is to you.
I'm not sure whether this is a good move by Google. People want to have better results appear on the search pages from various information sources; not necessarily from the sites they visit frequently.
