I have a question related to Google SERP and the way Google is showing their search results differently if I am visiting google.com through Chrome, Firefox or other browsers? I'm not completely understanding why this is happening and which results who are the "correct"? Why isn't Google showing the same search results? Perhaps some of you Google specialists can answer my question? Thanks in advance!
Google is known to have multiple data centers to handle search queries and equivalent responses. Having said that, it is normal to get different results between IPs as they might have been assigned with different data centers to handle them. Of course, this response is somewhat off course to what really was the question. And so here is what I think is happening between browsers. As we all know, google check on your browsing history and they do this with support coming from the browsers. You are not using all these browsers regularly to surf the net instead only your favorite which is either firefox, opera, safari, ie and any other. The more you use your favorite browser, the more crowded your history would become for that browser, feeding google a lot of phrases variations to respond accordingly to your next or future queries (which causes the rearrangement of results based upon your interaction with the browser and the keyword frequency detected everytime you search or access sites). This would then set a distinction between browsers in terms listing results as google would acquire different browsing behavior on each leading to more varied results among them.
This question has been asked multiple times here in Digital Point. You can use the search function to look for related threads. Or you can watch a video from Matt Cutts explaining why it shows different results on different browsers. http://www.w7b.org/search-engine-news/are-google-serps-the-same-on-all-browsers.html
