1. Use Doorway Pages - Google defines doorway pages as those that are large sets of poor-quality pages where each page is optimized for a specific keyword or phrase. Google always frowns upon manipulating search engines and deceiving users. In 2006, BMW suffered Google’s wrath for setting up doorway pages to attract search engines and redirect traffic to its German website, BMW.de. BMW’s page rank was reduced to zero. While BMW stated it did not intend to deceive users, the company added, “However, if Google says all doorway pages are illegal we have to take this into consideration."
  2. Selling links that pass PageRank violates Google’s quality guidelines; this includes advertorial pages with embedded links that pass PageRank. Google recently penalized Interflora, even removing it from branded search results, for using advertorials to solely influence search rankings. An example of this, is that Interflora reportedly sent bloggers floral arrangements in exchange for links. This was once considered a gray area, but is clearly black hat now.
  3. Scraped Content - In 2012, Google blacklisted a network of websites run by the family of U.K. Parliament member Grant Shapps after the search giant found the sites breached rules on copyright infringement and that they were based on scraped content. This latter black-hat tactic is typically when webmasters use content from other sites to try to increase credibility and the volume of pages.
  4. If your site belongs to a blog network whose purpose is to create backlinks, Google will de-index them and penalize you. In 2012, this happened to Build My Rank, which ultimately closed down and relaunched as HP Backlinks. The relaunch, however, has many people wondering if (and when) Google will go after the network again.  Your best option is to not purchase backlinks.

Keep in mind that when you get those email and calls from companies saying they can make you number one on Google, they are probably using some of the tactics that we have discussed over the two posts, so steer clear and use a reputable web company to handle your online presence. You will be glad you did.
