Im starting some blog and want to know if i need to gat baclinks as any other sire or, because its blogger, google will index it by itself. Thanks
You still need to build links. Google does not automatically index Blog Spot blogs. They work just like any other blog or website. You can also just submit it to Google for inclusion but it is always better for them to find it through quality back links.
Google will find it eventually. But if your blog's niche is not very unique (that is, if there are a lot of websites about your topic, and those sites are bigger and have more traffic than your blog), then you will be way the heck down in the page ranking and no one will ever find you by searching in Google. Getting those links will move your site up in the rankings... and more importantly, help some freaking people find your freaking site in the first place.
That was the best explanation so far... Try also submitting to blog directories, but I suggest that you choose the NO RECIPROCAL LINKS REQUIRED as some directories die instantly.
Google will index it as it is a subdomain on blogger www.XXXX.blogspot.com you will still need to get backlinks
