Google has recently announced a way of making searches more personal. What impact is this going to have on Search Engine Optimisation (SEO)?
When you perform a search on your computer, the search engine results pages (SERPs) that Google gives you are “organic”. In other words, the terms that appear highest on the list are the ones that Google judges to be of greatest interest for everyone in general.
In the SERPs, Google is determined to preserve the impartiality of its rankings. Yet in other situations, Google will try to provide you with what it thinks is going to be of most interest to you personally.
The latest innovation announced by Google will allow you to personalise your web search with stars. If you bookmark a page using the bookmark or star icon, then the next time you perform the search, the item will appear at the top of your results.

What impact might this have on SEO? The point of SEO is to get your company to the top of the page for a term that is relevant to your business. Will stars affect how Google perceives your site?

Businesses already ask their website visitors to “Bookmark this page” or “Add to favourites”. I suggest you make sure that you include Google Bookmarks in the options of bookmarks for your site.
