Google tries to keep its search results as clean as possible. For that reason, they have a variety of spam filters in their ranking algorithm that try to remove low quality web sites.

If your web site gets caught by one of these filters, it will be very difficult to get high Google rankings. In this article series, we're taking a look a the 15 most common Google spam filters and we'll tell you how you can get around them.

Google's -30 filter, the Google bomb filter and the page load filter

Google seems to apply the -30 filter to web sites that use spammy SEO methods. If Google finds out that your web site uses invisible text, JavaScript redirects, doorway pages or similar spam techniques then your rankings will drop by 30 spots.

The Google bomb filter seems to be applied to web sites that get too many identical links in a short time period. If a web site gets many links with exactly the same link text then Google will downrank the page because such an unnatural linking behavior indicates a manipulation attempt.

The page load filter is not exactly a filter. Nevertheless, it can affect your Google rankings. If your web site takes too long to load then the search engine spiders will time out and continue with the next web site in the list. That means that your web site won't be indexed and that it won't appear in Google's result pages.

How to get around these filters

If the -30 filter has been applied to your web site then you must remove the spam elements from your web site. After removing the spam elements from your site, send a reinclusion request to Google.

It is very important that all spam elements have been removed from your site before contacting Google. Otherwise, the reinclusion request won't work. Use white-hat SEO methods to optimize your web pages.

If the Google bomb filter has been applied to your web site then you also have to file a reinclusion request. However, it is better to avoid that Google applies that filter to your site. Try to get high quality inbound links with similar but varying link texts. These links will tell search engines that your web site is relevant to a special topic.

If you want to avoid that a slow loading web page prevents search engine spiders from indexing your page, make sure that you have a reliable web host. If your web host offers 99% uptime then this means that your web site can be down for nearly 4 days per year. If search engines try to index your site when it is down then it will be removed from the index.

Google's link farm filter, the broken link filter and the too many links filter

Google heavily relies on inbound links to determine the position of a web page in the search results. To make spamming as difficult as possible, Google also have a variety of link filters to make sure that only the right links are considered.

Participating in a link farm system won't increase your search engine rankings. Actually, you can hurt your rankings if you link to a link farming scheme.

The broken link filter is not actually a filter but the effects are the same. If you have broken links on your web pages and if not all pages on your web site can be found through links on your web site then Google cannot index all of your pages.

Many broken links also indicate that your web site is not very professional and that it should not be listed in the top results.

The too many links at once filter is applied when your web site gets very many links in a short time period. Too many links at once can lead to problems with all big search engines, not just Google.

How to get around these filters

Don't use link farms to get links to your web site. Better use a serious tool to get high quality links to your web site. Do not use black-hat techniques or link spamming to avoid getting caught by Google's too many links at once filter.

To make sure that the broken links filter is not applied to your web site, make sure that all links on your web site are intact and use a sitemap so that search engines can find all pages on your web site quickly and easily.

Google's Sandbox, Google's Trust Rank and Google's domain age filter

These three Google filters all take a look at the age of a web site. Many web sites don't get very old. For that reason, Google implemented a filter that prevents new web sites from getting high rankings for competitive search terms. That filter is called Google's sandbox.

Google's TrustRank filter is closely related to that filter. Web sites with a high TrustRank get high rankings on Google. The TrustRank of a web site is determined by the age of a web site, the quality of inbound links and the contents of a web site.

The domain age filter is another filter that considers the age of your web site. Web sites with old domain names are more likely to get high rankings for competitive keywords on Google.

How to get around these filters

It's not easy to get around these filters. As they all consider the age of your web site, you basically have to wait some time until Google releases your web site from the sandbox.

The best thing that you can do is to work on the content of your web site to show Google's web page spider that your web site is a valuable resource for your topic. Make sure that your web pages are relevant to your search terms.

In addition, get good inbound links to increase the TrustRank of your web site. The better the links to your web site, the higher your TrustRank and the higher your web site will rank on Google.

Everyone wants to have a successful web site. However, most people do the wrong things to promote their web sites.

If you want to have a successful web site and if you want to get high rankings on search engines then your web site must have the right factors. Here are the top 5 factors for successful web sites in 2007:

Success factor #1: Accessibility

Search engines must be able to access your web pages. If search engines cannot parse your web pages then they will ignore your site and you won't get good rankings.

Make sure that your web server doesn't return an error code when search engine spiders visit your web pages. If your server returns an error code, search engines won't index your site.

The correct code should be "200 OK". You can check the status code that your web server returns to search engines with IBP's search engine spider simulator (free).

In addition, make sure that the HTML code of your web pages doesn't contain errors that prevent search engines from indexing your site.

The content of your web pages must make sense to search engines. Don't use images or Flash to present the main content of your web pages. Use IBP's Top 10 Web Page Optimizer to find out if your web pages present the right information to search engines.

Success factor #2: Site and information architecture

Your web site should have a good site architecture to make sure that it is not just a collection of random web pages. The pages of your web site should be related and they should show search engines that your web site is relevant to a special topic.

This is very important because most major search engines seem to use latent semantic indexing in their ranking algorithms.

Your site should also have a good information architecture so that search engines and web surfers know where they are within your site on any page of your site.

Success factor #3: The right keywords

Choosing the right keywords is one of the most important steps that determines whether your SEO campaign is a success or not.

It's best to focus on 2 or 3 word keywords for search engine optimization. One word keywords are less likely to convert to a sale and they are also much more competitive.

Use IBP's powerful keyword tools to find the keywords that will work best with your site.

Success factor #4: Content

Web sites that only offer articles and affiliate links that can be found on dozens of other web sites will have a hard time to get good search engine rankings.

Try to create unique and trustworthy content that separates your web site from the others.

Write about things you know. If you're an expert in a special field, write as much as possible about that field to make sure that your web site becomes the best resource for that topic.

Success factor #5: Inbound links

Without good inbound links, it is impossible to get high rankings on major search engines. You should get as many links as possible from related web sites. The more targeted the link, the more it will help your search engine rankings.
