Click-through rates, bookmarks, RSS and other behavioral factors
The click-through rate of search results is also a very important search engine data. If 8 visitors click on the first result, spend 30 seconds, and after clicking, go to the second result and spend five minutes there, that's a good indicator for the second search result. Because users are more willing to pay attention to their website. The purpose of a search engine is to allow users to find websites that are useful to them and give them information they are willing to spend time reading.
Google also has its own Reader and Toolbar, which can collect data about user behavior. If 1000 users offer similar subscriptions and start spending a lot of time on a specific website, say www.qqai8.com. Then the weight of this website will also increase.
Google is already starting to use this data for something called "personalized search." I believe they are still in the process of analyzing, developing the algorithm, testing and tweaking. This will certainly be a very important factor in the coming years.
Age and relevance of external links
The age of the link. One link is 1 year old and the other is 2 years old. It is obvious that links that have been around for 2 years have extremely high weight.
Relevance of the link. The most effective links are when they come from a relevant topic page. For example, QQ Love Bar includes QQ Space and QQ Personalized Signature. The webpage topics linking to QQ Love Bar should preferably be related to QQ Space.
Search domain names and website names directly
If thousands of people enter www. xxxx .com in the search box, they will directly search for your domain name. Google will also think that the weight of this website is relatively high. Adding link growth and other trust factors over time can also help rankings.
