The plus1 button is intended for individuals who wish to confirm that they like, respect or would recommend the information presented on the web page they may be visiting.
This advice will carry different quantities of weight to other people, depending on whether they know the person that is +1-ing something. So if a notable baseball player +1’s a newspaper’s review of the early baseball season at a national newspaper’s sports area online, then that is going to matter to those thinking about that sports activity. To someone else, it won’t matter as much, if at all.
Additional to this, a Google+ profile page can be connected to other related sites and this profile page (which can represent a person or a business buy google plus followers, for instance) can be linked to a team of other profile webpages (known as a circle) and this then can affect what content each one of the people in the circle are shown subsequently when conducting searches within Google itself.
Initially, people were unsure. However , Google themselves have since confirmed that they do incorporate social press signals into how they rank web pages for various search terms.
Recent independent research at Tasty Placement was setup to try to confirm if the number of Twitter followers, twitter updates & retweet, Facebook stocks and likes, Google plus1 voting and the number of followers to a site’s Google+ business webpage were material in search result positioning. Of the six sites tested, five demonstrated a jump in positioning from 1 to 16 places higher, where as one site which got no social media activity added, dropped a position. Similar research elsewhere has also shown the same outcomes.
In testing, the strongest movement was actually caused by an increase in Google+ profile followers, followed by increases in +1 voting itself. The particular control number was a 100 follower increase for a certain page and 300 +1’s, and these had the highest effect on results.
Google is starting to be able to piece together the mosaic of the web, to see how one business page connects to one person (they work at the business they url to, from their Google+ profile) which in turn attaches to +1’s made by the same person.
Google’s own search engine results pages (SERPs) are now including highly personalized ratings, that rather than being fixed for those visitors, are now personalized. The degree of personalization varied, and it bears over from +1’d pictures, videos and written content, links to Google+ profile and pages that contain been visited previously. If a page or a site is well liked by people added to a circle, then it is more likely that this page will show in a higher position for those in the circle that it most pertains to.
