176. Panda Penalty: Sites with low-quality content (particularly content farms) are less visible in search after getting hit by a Panda penalty.
177. Links to Bad Neighborhoods: Linking out to “bad neighborhoods” — like spammy pharmacy or payday loan sites — may hurt your search visibility.
178. Redirects: Sneaky redirects is a big no-no. If caught, it can get a site not just penalized, but de-indexed.
179. Popups or “Distracting Ads”: The official Google Rater Guidelines Document says that popups and distracting ads is a sign of a low-quality site.
180. Interstitial Popups: Google may penalize sites that display full page “interstitial” popups to mobile users.
181. Site Over-Optimization: Yes, Google does penalize people for over-optimizing their site. This includes: keyword stuffing, header tag stuffing, excessive keyword decoration.
182. Gibberish Content: A Google Patent outlines how Google can identify “gibberish” content, which is helpful for filtering out spun or auto-generated content from their index.
183. Doorway Pages: Google wants the page you show to Google to be the page that user ultimately see. If your page redirects people to another page, that’s a “Doorway Page”. Needless to say, Google doesn’t like sites that use Doorway Pages.
184. Ads Above the Fold: The “Page Layout Algorithm” penalizes sites with lots of ads (and not much content) above the fold.
185. Hiding Affiliate Links: Going too far when trying to hide affiliate links (especially with cloaking) can bring on a penalty.
186. Fred: A nickname given to a series of Google updates starting in 2017. According to Search Engine Land, Fred “targets low-value content sites that put revenue above helping their users.”
187. Affiliate Sites: It’s no secret that Google isn’t the biggest fan of affiliates. And many think that sites that monetize with affiliate programs are put under extra scrutiny.
188. Autogenerated Content: Google understandably hates autogenerated content. If they suspect that your site’s pumping out computer-generated content, it could result in a penalty or de-indexing.
189. Excess PageRank Sculpting: Going too far with PageRank sculpting — by nofollowing all outbound links — may be a sign of gaming the system.
190. IP Address Flagged as Spam: If your server’s IP address is flagged for spam, it may affect all sites on that server.
191. Meta Tag Spamming: Keyword stuffing can also happen in meta tags. If Google thinks you’re adding keywords to your title and description tags in an effort to game the algo, they may hit your site with a penalty.
