On-Site Webspam Factors
172. Panda Penalty
Websites with low-quality content (a result of non-expert content writers) often get penalized on the SERPs. These websites get less visible on search engines after the panda penalty.
173. Links to Bad Neighborhoods
This is not a major ranking factor but outbound links from your site to websites in so-called “Bad Neighborhoods” could affect negatively.
174. Redirects
This is also known as cloaking. This refers to the difference between the content and code shown to search engines and users. Such redirects are a big no.
175. Popups or “Distracting Ads”
We all know how irritating popups or ads on websites are. Google has officially declared that popups and distracting ads are a sign of low-quality websites.
176. Interstitial Popups
Interstitial popups refer to the popups that appear all over the display. These pop-ups can result in a penalty by Google. According to Google such practices can hinder easy access to content.
177. Site Over-Optimization
It is true that Google will penalize or deindex sites that are over-optimized. Over-optimization includes things such as keyword stuffing, title tag keyword stuffing, meta description stuffing, etc.
178. Gibberish Content
Gibberish content does not help users and is easily identified by Google. Gibberish content can be spun content that is auto-generated and Google can identify it within its algorithm.
179. Doorway Pages
Doorway pages are the ones that are redirected from an existing page on a website. If a page on a website is redirected to another page it is called a ‘Doorway Page’. Google doesn’t like the use of excessive Doorway Pages.
180. Ads Above the Fold
Ads above the fold mean a site getting bombarded with display advertisements. Google may penalize sites that have too many ads with less content.
