When an enterprise optimizes its search engine, the principle of capture capture is to sort -- capture -- index -- search word processing -- and each step has his core points. If you want to get a page listing and get a ranking, we need to think about how the search engine works, and the d. M. A. P. Below will show you how to optimize the seos for marketing。
I. Crawling and grabbing
First, we need to know that if the search engine spiders are to climb and grab a page, you have to meet two features: first, sufficient external chains; and second, the frequency of website updates. Each station within the 100-degree platform will have a frequency, and the frequency that captures can be seen specifically as the extent to which the site is loved by spiders, or the higher the common understanding of the site, the higher your site is loved by spiders, the faster your entry. I think it should be clear if you use a programme like a spider pool, but many friends, even if they use a spider pool, are just outside links to attract spiders, and if it's more effective to update the frequency with a site!
Ii. Accountment and rules
It is usually understood that there are no significant differences between page entries and page indexing, but in fact there are two situations in the entire site document:
1, url entries -- yes, index -- no; the representative has entered the index, except that the “weight” on this page is very low and can be considered an “invalid index”。
2, url entries - yes, index - yes; representatives are eligible to participate in the ranking but do not guarantee 100 per cent access to the ranking and can be considered “effective index”。
We can simply understand that the site page out of the site is recorded, but it doesn't mean that the page out of the site is indexed.
Access and ranking
The two most commonly used search engine principles are reflected in the entire search and ranking, the reverse index and the tf-idf algorithm. The tf-idf algorithm is the frequency in which the key words of the page document appear. And this algorithm can be used to calculate the number of word frequency occurrences in a file set, thereby assessing the importance of a page. This is important in combination with the title page, where it is often said that the content of an article is relevant to the subject matter of the page title, similar to the subject matter of writing。
From the page to the search ranking, i have several steps:
Regular updates to allow spiders to grab frequent grabs are recommended to submit site maps to 100 degrees and update site maps on a regular basis。
2. To make the page more fresh and responsive to the needs of users by articles and by changing the title and layout。
3. Maintaining a large number of daily updates to make spider capture a habit。
4. Old domain names, combined with the accumulation of original site data, maintain site authority and thus have greater capture advantage over new domain names。
