How to Increase a Website's Indexed Page Count

　　In order to crawl as many pages as possible, search engines automatically follow the links on pages, usually by means of two traversal methods: breadth-first and depth-first. Theoretically speaking, whether a depth-first or breadth-first strategy is used, as long as the spider is given enough time, it can crawl the content of the website's pages; but in reality, the bandwidth resources, server resources and so on of a search engine spider are all limited, so from a practical standpoint the spider can only crawl a small portion of the content of the pages on the Internet, and there is still a very large number of pages that the spider cannot crawl.

　　So under this situation of fierce competition among websites, how can we increase a website's indexing by attracting spiders? SEO学堂 believes that if you want your website to be crawled as much as possible by spiders, you must find ways to attract spiders to come to your website and crawl it. Since search engine spiders cannot crawl all pages, they will crawl some important pages. Specifically, which pages will be regarded by spiders as important? There are the following influencing factors:

　　Websites with high authority, fast content updates and high quality, and a long history will be regarded by search engines as the websites to be crawled first; because such websites are usually crawled by search engine spiders on a priority basis, both their home pages and inner pages will be indexed in large numbers, and their indexed snapshots are updated quickly.

　　Websites with fast update efficiency. Once a spider has put your site into its index database and trusts it, it will frequently come to such a site to check whether there is any newly updated content; if there is updated page content, and many new links appear on the pages, then the spider's speed of indexing updates will increase accordingly; conversely, the efficiency of updating indexed snapshots will be greatly reduced.

　　Many and widely distributed inbound links. External links and internal links — for a page to be crawled by a spider, there must be an inbound link leading into the page; otherwise the spider has no chance at all of knowing that the page exists. Sites with many and widely distributed inbound links are usually crawled by spiders to a correspondingly greater depth.

　　Links on the home page carry relatively greater weight. Spiders generally hold that a website's home page has the greatest weight, so the closer a link is to the website's home page, the higher the weight of that page will likewise be, and the greater the probability that it will be crawled and indexed by spiders.

　　The purpose of learning SEO is to apply SEO. From an analysis of the crawling principles of spiders, if a new site wants to be quickly indexed by spiders, it should increase its website update frequency, provide users with more high-quality articles, and at the same time widely develop external links and do a good job of on-site link optimization; in this way spiders will naturally and quickly build up trust in your site, thereby improving your site's indexing efficiency and further achieving the goal of improving your website's SEO keyword rankings.
