Google customization is the newest little perk that this massive search corporation has added to its repertoire. Google's innovators are constantly trying to increase their already huge dominance in the search market, and here's their latest ploy.
In your search results, you will now see small icons depicting an arrow, an X and a speech bubble. These each represent different things you can do.
To begin with, the arrow beside the title of each listing is called the "Promote" button, which allows you to basically put this result at the top of your page. This is great for debate or thesis research because you can place all of the most reliable sources at the top of your page for easy access.
On the other hand, the X, dubbed the "Remove" button lets you demote a website to the bottom of your results. You can employ this as a sort of pop-up blocker, in order to ensure that you ignore web pages with huge amounts of advertisements.
Combined, these two features can be utilised as an alternative to bookmarking on your browser or with such services as del.icio.us (now known as Delicious). So your favorite sites won't only be in a small list but a big list. Namely, the biggest list on the internet, Google.
Now, don't think I forgot about the last symbol, the speech bubble. This, the "Comment" button lets users essentially give public feedback about a listing to help out other searchers.
Lastly, recently Google introduced a one more way to personalize your own results: You can now quickly and easily add a specific URL to your results.
But don't abuse these tools; if you do your searches may soon become inaccurate and messy. Of course, it consumes much time rating and commenting on each individual site so I don't recommend you do that.
Still, what Google has made can be very useful as long as you use it wisely.
