Do the crawlable pages affect my blogs rank in search engines?
Essentially, you will have two or more versions of your blog post indexed by search engines. As a result some bloggers may notice their articles appearing more than once on search results pages. Many factors go into determining which order a search engine displays results, and it is therefore impossible to predict where your original post or syndicated posts may fall. Having crawlable pages link back to your blog can increase your blog’s SEO value, as backlinks from high PageRank sites are generally valued by search engines.
