How often should a Search Engine resubmission performed?
The frequency of resubmission depends on the specific needs of your business. If you just completed a significant revision of your site, you may want to get your updated pages submitted to and listed in the search engines. If you operate in a highly competitive industry that relies on its web site for generating revenue, a monthly resubmission may be required to maintain a top position. If your site is not business critical, a quarterly or annual resubmission may be all you’ll need just to make sure your keywords and other meta tags are up to date and your site is optimized to score well with the latest search engine programs.
