It seems that from our little experiment, when you use social bookmarking for your posts, Google indexes them much faster. Â The post on the fictitious Â Ramadebolow fruit was indexed by Google in about 2 hours (see below). We had to do a time conversion. When we posted that article, it was June 27th and the time was 12.57 pm. That worked out to being 2.27am GMT and this post was indexed at 4.27 GMT. So all in all it took about 2 hours or so.
Interesting side note was that we used our Blogger account as one of the social bookmarks and that was indexed pretty much within the hour. It goes to show how powerful that platform is if you want to get your content out there quickly.
