The best way to avoid being blacklisted by
search engines is to avoid using some questionable techniques that were once popular to gain high rankings. Even if your website is not blacklisted by using some of
techniques below, it may be penalized (buried in
rankings) so your traffic will suffer all
same. When a search engine blacklists a website it will throw your listing off their site and block your site from coming aboard again. This can be done by blocking
domain name,
IP address or both.Here are a few techniques to avoid, so that your site will not be blacklisted:
Mirror Websites
Mirror websites are sites with identical content but different URL's. This was once a method used to gain high rankings in
search engines, but since search engines are smarter now, this will only get you penalized or blacklisted.
Doorway (gateway) Pages
Doorway pages are pages with little real content for your visitors that are optimized to rank highly within
search engines. These pages are designed so that visitors will move deeper into
website where
real content lies. Navigation to
doorway pages are usually hidden from
visitors (but not
SE robots) on
homepage.
Invisible Text and Graphics
Using invisible text (text
same or a very similar color to
background) was once used to spam a homepage and some inside pages with non-stop keywords and keyphrases. Also links to doorway pages and hidden site maps can be done with invisible text (or invisible graphics). Some designers will create a graphic link with a 1 pixel by 1 pixel raster image and link this to a hidden inner page such as a hidden site map.
Submitting Pages Too Often
Submitting
same pages to
search engines within a 24 hour period can get you penalized and may delay your website from being listed in
rankings. Some search engines believe that pages submitted sooner than every 30 days is too much. The 30 day rule is a good rule to follow when submitting to multiple search engines.
