I know how the search engine works

Today more leisurely oh, read a lot of feeling are not thinking, is not a good phenomenon. Reading is a thought, not a proportion. The work is endless, take a time to read the book, just Fuller.

Do you know why you need to understand how a search engine works? Learning a lot of things starts with the principle. It should be clear as a technician. The

Search engine quickly and comprehensively collects the question of the page: the page link is missing, there are too many flash JS. Every day there are a large number of web site information changes, search engine task is also very heavy, if a page always appear a variety of bugs, search engine will choose to give up. In fact, this is with us to see other people's program, or the teacher to see the students ' homework, their task is very heavy, but you get this task is all the problem, you feel the need to waste time to read it? So when we build the station, we will do all these problems, in the release. When accessing any page, the server returns HTML code, and the Spider Bar code program is stored in the original page database to access any page starting from robots.txt. I do not understand the working principle of spider crawling, just understand that crawling into the depth of crawling and the breadth of crawling, literally can understand the two ways. At present, in order to crawl all-round and reasonable, the two crawling methods are used together. What does

do to attract spiders?? Everyone wants to crawl their site pages, but not all sites have the opportunity to be crawled. Maybe your site has been optimized for a year and there is no home page, but we can choose some of the more important pages to do optimization.

The following are the factors that affect the site's inclusion: Weight on sites and pages, page updates, import links, and the distance from the first page. There's really not a bit of a concept before that. It turns out these are all factors of influence. So, change is to learn more ah ...

There is a question, the site will generally crawl first page, but how to optimize the home page to do the best?

Really see more is not necessarily good, see the past also can't remember, temporarily remember also not necessarily later remember, so see time must understand, write their views, deep in the heart, Do the finishing.
