Deceptive redirects: If you include links to affiliate programs on your website, you should know that Google considers them "deceptive redirects." Although there is no problem with having an affiliate link, bombarding visitors can affect the quality of the page. 

Spam content: There are many aspects that Google urges testers to look at when it comes to page quality. The use of a bad sticker printing landing page and self-generated content are factors that can lead to evaluators rating us as low-quality pages. 

Overuse of keywords: In general, we associate the overuse of keywords with cumbersome and unreadable content. However, Google also considers an excessive use of keywords when the insertion of keywords in the text is annoying for users. If you've thought about inserting more keywords from the account into your content, you should reconsider with this point in mind. 

Copied content: It shouldn't come as a surprise, but many people still think that unless a person makes a direct comparison, they can live with copied or 'borrowed' content. It doesn't matter if you copy or "scratch" content. Google asks its reviewers to analyze whether or not the content adds value carefully. Google also gives them instructions on finding duplicate content using the search engine and the "Wayback Machine" tool. 

Dropped: We keep finding web pages with forums full of spam, where there is no moderation on blog comments (full of self-approved pharmaceutical spam) or that have been hacked. Although the content may be great, this denotes that it is an unreliable website. If the website owner doesn't care to avoid this, why would a user trust the web? 

Fraudulent sites: If a page asks for excessive personal information, or is for a scam, or is a phishing page, they have all the signs of being a poor quality page. Also included in this type are pages with suspicious download links. If you offer a download, make sure it is entirely legitimate, or use a third-party verification service to provide the download.
