Google Wants To Rank High Quality Websites

Google has a history of classifying your site as some type of entity, and whatever that is, you don’t want a low quality label on it. Put there by algorithm or human. Manual evaluators might not directly impact your rankings, but any signal associated with Google marking your site as low-quality should probably be avoided. If you are making websites to rank in Google without unnatural practices, you are going to have to meet Google’s expectations in the Quality Raters Guidelines.
According to Google: "Low-quality pages are unsatisfying or lacking in some element that prevents them from achieving their purpose well."

Reasons

There is ‘sufficient reason’ in some cases to immediately mark the page down on some areas, and Google directs quality raters to do so:

• An unsatisfying amount of MC is a sufficient reason to give a page a Low-quality rating.
• Low-quality MC is a sufficient reason to give a page a Low-quality rating.
• Lacking appropriate E-A-T is sufficient reason to give a page a Low-quality rating.
• Negative reputation is sufficient reason to give a page a Low-quality rating.

What are low-quality pages?

When it comes to defining what a low-quality page is, Google is evidently VERY interested in the quality of the Main Content (MC) of a page.Some reasons are given below that cause your web page Low-Quality.

1. Poor Main Content & User experience

• This content has many problems: poor spelling and grammar, complete lack of editing, inaccurate information. The poor quality of the MC is a reason for the Lowest+ to Low rating. In addition, the popover ads (the words that are double underlined in blue) can make the main content difficult to read, resulting in a poor user experience.
• Pages that provide a poor user experience, such as pages that try to download malicious software, should also receive low ratings, even if they have some images appropriate for the query.

2. Poor Secondary Content

• Unhelpful or distracting secondary content that benefits the website rather than helping the user is a reason for a Low rating.
• The secondary content is distracting or unhelpful for the purpose of the page.
• The page is lacking helpful secondary content.
• For large websites, secondary content may be one of the primary ways that users explore the website and find main content, and a lack of helpful secondary content on large websites with a lot of content may be a reason for a Low rating.

3. Distracting Advertisements

For example, an ad for a model in a revealing bikini is probably acceptable on a site that sells bathing suits, however, an extremely distracting and graphic porn ad may warrant a Low rating.
