List of mistakes building anchor text:

• Building links with the same anchor is the fastest way to be punished by search engines. Webmasters without experience don’t realize that this strategy called “keyword spam” and #1 sign for Google that website are targeting top positions. To avoid “keyword spam” you should pick at least 5 different keywords to build backlinks. For example: Security supplies, emergency supplies, security products, affordable security supplies, emergency and disaster equipment.
• Asking webmaster who already gave link to change anchor text because you feel like you can rank better with different keywords. Once Google indexed backlink they don’t appreciate any changes in anchor, any additional changes lift “red flag” which shows that webmaster are trying to fix results.
• Long anchor text stuffed with keywords is nothing but punishment. It is fine when backlink contain long anchor text which represents title of the post or page. Anchor text like “Steve Jobs (Apple) introduced new iPod and iBook on February 10, 2008” is fine for search engines because it tells exactly what page is about. Anchor like “Apple, iPod, new iPod, Steve Jobs, iBook, Steve Jobs Apple, Apple iPod” is 100% spam which can destroy website rankings and bury domain trust.
• Grammar mistakes in anchor text… millions people was trying to do the same thing before and search engines filter links like this right away. You can lose domain trust, positions, and power of your backlinks right away.
• Building backlinks with anchor which doesn’t represent content on your site is the easiest way to get penalized. This strategy worked back in 1996; people who work for Google, Yahoo, and MSN had enough time to create algorithms which remove this type of spam.
