Seo is actually very scientific.

When it comes to science, some children's shoes will ask-Can Seo really be very scientific? We often encounter some seoer. The answer to some questions is: I think yes, it should be, it seems to be .......... This is very unscientific. No matter what problems you encounter, his answer must be very scientific. Data-data is the dialectical person with the most theoretical basis. Through data, we can see all problems at a glance. We can talk about all the things that affect Seo through technology.
Factors of data, combined with the user's hearts and habits, will be obtained from the search engine to maximize the benefits, So Seo is also a technical work, if a non-technical seoer is definitely not good at Seo, it is an era of data-based speaking, not a time of conjecture.

Scientific Seo is definitely not a scientific Seo system. The so-called Seo system is how your SEO traffic comes from --

[Seo traffic = overall x overall ranking X Overall click rate]

(1) What is the overall indexing volume:

(2) overall ranking/overall click rate:

Overall ranking refers to the ranking statistics of a large number of keywords to obtain an index after Comprehensive weighting.
Ranking quality score. Specific algorithms will be posted separately for discussion.

Overall CTR = clicks/impressions

What we know about these basics is how we do it? We will take the record as an example. Here we will confirm the common sense: (1) only 24 hours a day; (2) it takes some time for a crawler to download a page.
. Although there are a lot of baiduspider and googlebot, there are limits on the time each spider crawls every day, and it is impossible to crawl without limit. Next we will talk about the amount of crawlers:

Capture volume =
Total crawler stay time/download time per page

Total crawler stay time = average crawler stay time x
Crawler quantity

We can analyze the number of crawlers and a series of data based on the log analysis system of lightyears. The data is clear at a glance. You can try out the useless shoes. After learning about the crawling time and rules of a spider, we have to consider another question. How can we attract the spider to crawl my page? We can --

(1) Reduce the download time for a single page. This may require our technology and front-end optimization.
Cache Technology CDN...

(2) increase crawler stay time-one way is to increase the internal weight of the website, that is, to provide more content that crawlers have never seen before, so that they can continuously crawl your webpage,
Another method is to increase the external weight of the website, that is, capture data through external links.
.

(3) increase the number of crawlers-allow more crawlers to crawl your website, which has a lot to do with your server and CDN, if your server has high performance and high speed, crawlers are very happy to crawl.
