GOOGLE Optimization: several simple methods to improve domain name trust

I believe that readers know that Google has higher and higher requirements on domain name trust, or even too high.
However, complaints are useless and must be faced with reality.
In general, the fundamental way to improve domain name trust is to provide good content and attract other domain name links with the same credibility to you. These two items are both time-consuming and labor-consuming, and cannot be done in a short time.
There are also several simple ways to do this. Try again.
1) websites must have privacy policies
I don't need to look for my blog's privacy policy. I haven't added it yet because the whole website is not ready yet.
2) provide complete contact information
Including telephone and real address.
3) before having a lot of good content, you should at least make the website more than 40 or 50 pages.
4) link to several authoritative websites in the same industry
The above four points came from a major change in Google Adwords's entire bidding system two months ago. In the past, Adwords ranked ads based on the price and click rate. In July, Google informed Adwords customers that the quality of the website will be recorded in the entire bidding system, the cost for low-quality websites is high.
Many webmasters have reported that this change requires them to pay more than two to three times the price to maintain the same advertising ranking.
After some webmasters contact Google, Google's answer is to improve the above four items. Although this is for Adwords advertisers, why cannot we use the same standards in rankings?
5) register the domain name for several more years, instead of renewing the domain name every year.
The Whois data of the domain name matches the contact information on the website. These two points have been mentioned in a Google patent application.
6) use an independent IP address
Most websites share an IP address on a VM. However, some people suggest that the independent IP address is a sign of high-quality websites, which is logical. But Matt Cutts once said, don't worry about this. You have to make your own decisions.
7) There are no or few dead links on the website, such as 404 errors.
8) fast server response
Reduce downtime. This should not directly affect the ranking. Unless you are on the machine for a week, the search engine spider will crawl your webpage in a few days. However, it is also logical to infer that if your website goes down for a large amount of time, it means you are not serious about the website and the quality may not be high.
9) The webpage HTML code has been verified by W3C
Reduce at least serious code errors. As Matt Cutts also said, you don't have to worry about this. Most websites have code errors.
These may be very small factors. However, this may have a slight impact. Why not do things that are easy to change?
