Highlights of website optimization and improvement in google rankings (Lite version)
 
Google's ranking algorithm mainly uses two parts. The first part is its text content matching system. Google uses this system to discover webpages related to search words typed by searchers. The second part is the most important part of ranking algorithm, namely Google's patented webpage-level technology.
The keyword that appears in the title is given a higher weight, so you should ensure that the most important keywords are included in the title tag of your website, that is, the content of the webpage title should be determined around your most important keywords. However, the webpage title cannot be too long. Generally, it is better to be between 35 and 40 characters.
Google will generate a description of a website from the first few lines of text on a webpage. That is to say, you 'd better put your keywords or key phrases above the web page, so that if Google finds them, it will increase the relevance of your website accordingly.
When determining the relevance of a website, Google will also consider the Keyword density Keyword of the text content in the webpage, but remember that the Keyword density of 6-10% is the best.
Other strategies for increasing page relevance include adding keywords in the title content and adding the keywords in the content as rough as possible. Google also indexes the ALT attribute text of the image and counts it into relevance calculation. Therefore, you should include keywords in your ALT attribute to increase the relevance score of the website.
The last trick to increase page relevance is to include your keywords in external text links on your website. Adding keywords to external text links can effectively improve the relevance score of your website.
The damping factor is the actual PR score you get when you vote or link to another site. The damping factor is generally 0.85. Of course, it is insignificant compared to the actual PR value of your website. Now let's take a look at the formula for calculating the PR score:
PR (A) = (1-d) + d (PR (t1)/C (t1) +... + PR (tn)/C (tn ))
 
Generally, an external link site with a PR score greater than or equal to 6 can significantly increase your PR score. However, if this external link site already has 100 other external links, the PR score you can get is almost zero. Similarly, if the PR value of an external link site is only 2, but you are the only external link, then the PR value you get is much greater than the PR value of 6, the number of external links is 100.
The problem now seems to be more and more complicated. It doesn't matter. Let's take a look at the formula below.
First, let's explain what is a damping factor ). The damping factor is the actual PR score you get when you vote or link to another site. The damping factor is generally 0.85. Of course, it is insignificant compared to the actual PR value of your website.
Now let's take a look at the formula for calculating the PR score:
PR (A) = (1-d) + d (PR (t1)/C (t1) +... + PR (tn)/C (tn ))
