Search Engine Optimisation techniques vary, from white hat techniques such as Link Building, Content Copy Writing and Blogging to black hat techniques bordering on SPAMMING. Googles main aim is to provide a trust worthy search service, presenting search users with a list of useful web sites based on their search criteria.
Some, although not all, of the known black hat techniques can quickly get you to the top of the Google rankings for your chosen keyword. In the short term you can yield some excellent results, enquiries and conversions, but you will find that eventually your site will drop like a stone or in the worst case scenario dissapear completely.
Why does this happen? You have been penalised by Google for using black hat techniques to promote your site.
This is one of the most frustrating things to happen for any SEO, or web site owner.
Depending on how serious your violations are (against the Google Webmaster Guidelines) depends on how serious your penalty is. In some cases you may only be blacklisted for a few weeks and you can correct your penalty by dropping your black hat techniques and working towards Googles Webmaster Guidelines. In the most serious cases web sites have been known to dissapear completely from the rankings forever.
There are two major levels of penalty that have been reported, the -30 and the -950.
The-30 penalty basically does what it says on the tin. It drops your web site ranking by 30 places. Minus 30 penalty is one that filters for handling spam in Google algorithm. The only solution to get around this penalty is to have unique content on your site, to get links from well trusted sites and to link to high quality sites.
The -950 penalty is a different beast altogether. It only affects precise URLs for particular keywords. However, the -950 is also the harshest penalty and web sites can be dropped to the bottom of the results for the given keywords. How can this be avoided? The only thing you can do is to stick to the Google Webmaster Guidelines and stick to White Hat SEO tactics.
If you have been penalised by Google then don’t take it out on the Search Engine. You have been penalised for a reason and it’s nearly always down to the techniques that have been used in an attempt to promote your web site.
