What are the reasons for the website being K

In fact, it is very possible for a site to encounter the phenomenon of being K if it is not careful. What are the reasons for being K? The New Start blog summarizes the following ten reasons for the website being K:

Modify the title: frequently modify the title, or change it beyond recognition (for example, website construction is changed to website construction)

Website revision: the program has been changed, and the path has changed.

Poor content quality: massive collection, pseudo original content with tools, or content unrelated to the website host.

Keyword accumulation: the target hit by search engines,

No traffic sites: included, not ranked, not maintained for a long time

Low user stickiness: unable to retain users, high bounce rate and low PV.

Poor user experience: poor page ranking and layout, many advertisements, affecting users' reading.

Mismatch: The content provided is irrelevant to the title, deceiving users.

Slow website loading speed: pages are not optimized well, and loading is slow (such as large pictures, flash, and too many JS CSS are not merged). Loading is completed within 5 seconds

The server is unstable: 500 503 code is often unable to be opened, and the speed is slow to load within 5 seconds

Poor server security: often hang up the horse for intrusion, and attack kills the server

Mass distribution outside the chain: mass distribution outside the chain with software (these belong to garbage outside the chain)

Friendship links: too many friendship links (within 45, within 35 of new stations) to K, buy a large number of friendship links or a large number of one-way links.

The outer chain increases too fast: suddenly a large number of outer chains are added

The above is easy to offend in the optimization process, leading to K station.
