I have a photo sharing website, which provides very little textual content. Users can add tags to photos and a description, but it creates a lot of duplicate content, because most of the descriptions will be 'wow', 'lol', ... I don't think I should rely on users to build my SEO.
I think it would be a great idea to write a blog, and use it to describe the best photos, start contests, explain themes, in short: create original content that search engines will love.
Our website's main URL is like
www.domain.com, and our new blog is hosted on
blog.domain.com. From a SEO perspective, is it a good idea to keep the blog separate from the main site? This has the advantage to leave the original site unchanged, but will it add any page rank to the
www.domain.com? If the blog ranks well it will obviously pass some page rank to the original through links.
What do you think is the best option from a SEO perspective? Include the blog in
www.domain.com? Or leave it in
