How often should we submit our web site to the search engines?

Answer 1

You should repeat the submission process at least once every two months or sooner if you have added substantial number of new web pages, or content to your web site. Over submitting to search engine can be considered spamming, to avoid this check your SEO Studio submission reports, or do a quick check by selecting the search engine from the submission tool list and the previous submission dates will be automatically displayed.
