My question for you guys is: Does submitting a single webpage or blog entry to too many social bookmarking sites hurt your SEO? I`ve recently been submitting each blog entry to 12 or 13 social bookmarkng sites, and I wonder if that`s too much. My SERPs have slipped a bit recently and I wonder if this could be the cause.
What's an appropriate number of sites to submit each blog entry or web page to?
Thanks for any help!
