There are a number of different optimization techniques webmasters use to try and improve their search engine rankings, some acceptable (white hat SEO), some not (black hat SEO).
Here is a screenshot of the page in question before the redirect is put to use.
As you can see, the “content” on this page is being used for one purpose: so TechGroups gets search engine credit for work that is not theirs. Because TechGroups.com offers SEO services, having a respectable rating for any keyword terms or phrases related to optimization (or any of the other below examples) will only benefit the site, provided they haven’t been penalized (which may be case because the TechGroups.com index page isn’t showing in a Google site query, unless of course its buried deep within the SERPs).
I’ve also just discovered that the search engine spam page is not the only page of this type being used by TechGroups. They’ve also included pages that target the following:
Add (which seems to target some of the following keywords: grossing films google page rank, page rank google, page rank algorithm ? sextracker page rank)
So that people who may unknowingly employ methods like these, Matt offers some high-risk tactics to avoid when optimizing your site:
Don’t use programs that automatically generate doorway pages. It especially looks bad if the doorway pages are gibberish. It really especially looks bad if the content you use is scraped content. If you’re considering scraping content, doing it in the SEO industries is one of the worst places to do it. If you scrape SEO content and end up scraping a couple spam pages, you may get noticed even more because someone is investigating the other spam pages.
