I recently posted about how swiftly Google indexes Blogger blogs. Makes Blogger a good choice for anyone who wants to get search engine traffic as soon as possible.
Another thought on how to speed up the process: be specific with posts. For instance, company and brand names are often searched, sometimes in clusters. I have received quite a few hits now from Google searches for "Weebly+Synthasite+Webnode" or variations thereof. If you can, put these kinds of words in the title of your post, listing two or three if it's appropriate.
Also, there's something I noticed while looking at the stats for my main site: people will often include a preferred location (city or suburb) in searches. Be mindful of this when optimizing your site.
