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.

Using Irrelevant Keywords

If you have any interest in getting high search engine rankings for your website (and who doesn't) you've probably been sold idea that writing and publishing your own articles will do it for you.

Here's why that's not entirely true.

Imagine following scenario...

You write an article around a keyword or keyphrase you want to rank well for.

You submit that article to all article submission sites and directories and ezines you can find.

Your article gets published in hundreds of places.

You now have hundreds of links pointing back to your main site...

But your own site never shows up in top ten results for that particular keyword or keyphrase.

Instead you find that there are lots of other sites carrying your article that rank better than yours.

You've completely missed out on an excellent opportunity to get high rankings for your keyword or keyphrase.

Even worse... you just handed your precious keyword-rich content on a platter to possible competitors who happened to publish your article on their website, and may have lost some of your most targeted visitors and sales to them.

So where did you go wrong?

Your mistake lay in using your precious article - keyword-rich content you toiled for hours to write - for entirely wrong purpose.

You failed to use power of medium of article publishing to give your site an unbeatable advantage over others.

Here's how to use your articles right way to boost your search engine rankings.
