Search Engine Quality GuidelinesIf you've done any research on search engine optimization, it's likely you've run across some questionable tactics. I think we've all been tempted to use the "flavor of the month" search engine tactics from time to time, especially when we see keyword stuffing sites or someone using "black hat" tactics taking over the top spots. While these tactics may work for a time, the engines WILL find them, WILL take steps to eliminate them, and WILL punish the site owners.
It's not worth it to get a good listing for a couple of months only to lose it permanently by using questionable optimization methods. The information below has been taken directly from Google.
Quality guidelines
These quality guidelines cover the most common forms of deceptive or manipulative behavior, but Google may respond negatively to other misleading practices not listed here (e.g. tricking users by registering misspellings of well-known websites). It's not safe to assume that just because a specific deceptive technique isn't included on this page, Google approves of it. Webmasters who spend their energies upholding the spirit of the basic principles will provide a much better user experience and subsequently enjoy better ranking than those who spend their time looking for loopholes they can exploit.
Quality guidelines - basic principles
- Make pages primarily for users, not for search engines. Don't deceive your users or present different content to search engines than you display to users, which is commonly referred to as "cloaking."
- Avoid tricks intended to improve search engine rankings. A good rule of thumb is whether you'd feel comfortable explaining what you've done to a website that competes with you. Another useful test is to ask, "Does this help my users? Would I do this if search engines didn't exist?"
- Don't participate in link schemes designed to increase your site's ranking or PageRank. In particular, avoid links to web spammers or "bad neighborhoods" on the web, as your own ranking may be affected adversely by those links.
- Don't use unauthorized computer programs to submit pages, check rankings, etc. Such programs consume computing resources and violate our Terms of Service. Google does not recommend the use of products such as WebPosition Gold™ that send automatic or programmatic queries to Google.
Quality guidelines - specific guidelines
- Avoid hidden text or hidden links.
- Don't use cloaking or sneaky redirects.
- Don't send automated queries to Google.
- Don't load pages with irrelevant keywords.
- Don't create multiple pages, subdomains, or domains with substantially duplicate content.
- Don't create pages with malicious behavior, such as phishing or installing viruses, trojans, or other badware.
- Avoid "doorway" pages created just for search engines, or other "cookie cutter" approaches such as affiliate programs with little or no original content.
- If your site participates in an affiliate program, make sure that your site adds value. Provide unique and relevant content that gives users a reason to visit your site first.
