It is well known that whether a website is well indexed is related to the frequency of spider crawling and the pages it crawls. However, we do not know which pages the spider has crawled, so we can only rely on the access logs crawled by the spider for analysis. We can analyze a lot of data from the log, so today I will mainly explain to you the factors that affect spider crawling and crawling time. Don’t underestimate this log, it can help you know whether the website means something to spiders. Friendly state, whether spiders like your website or not. If the number of crawls is large, then you can simply conclude that the website is very suitable for spiders. If spiders do not come for a few days, then you need to check whether it is the website. There is no "food" that spiders like. Here are the relevant points that affect crawling:
Factor 1 that affects spider crawling: whether there is a site map
For spiders, the website map is a crawling road map. When the spider has this road map, crawling on the website will not be so strenuous, and it will not feel dizzy at any time. The website map is specially used by spiders. The purpose is to reduce the spider crawling time and speed up the spider crawling speed. After all, if your website is not equipped with a map, it is like going to a strange place by yourself. Without a map, you have to rely on blind search. , I don’t know how much more time this will take. Therefore, in the same way, the website map is equally important to spiders. Don’t save anything without the map. It is the preparation before the war, the direction during the war, and the summary after the war.
The second factor affecting spider crawling is whether to set a 404 page
Many websites don't care about this at all. In fact, according to the author's actual experience, this is very important for a website with dead links, because it can help the website tell the spider that when it crawls to a dead end, give it to it. A way to come back to life, the 404 page is prepared to prevent spiders from entering a dead end and being unable to get out. Who can guarantee that their website will not have dead links? The impact of dead links on a website is very important. If The website has too many dead links and lacks 404 pages. When you use webmaster tools to query and analyze, you will find that many pages are crawled incorrectly. This shows that the website is not friendly enough to spiders and makes spiders Create a feeling of rejection. Therefore, a 404 page must be added to the website. It doesn’t take up much space anyway, so why not add it?
The third factor affecting spider crawling is whether there are too many exported links.
Too many export links on a website will have a great impact on the weight concentration of the website, and will have a great effect on the spider's stay time, because when a spider crawls your website, it usually crawls from the beginning to the end. Then the spider crawls sometimes according to the breadth crawling method, and sometimes according to the depth ranking method. When it crawls according to the breadth ranking method, it just crawls to the end but has not yet entered the inner page. If you give it an export link, then the spider will also Follow the export link. This is the reason why the spider you often see comes but does not include any pages. Therefore, the website should not set too many export links, as it will not bring any benefits to your website.
The fourth factor that affects spider crawling is whether there are too few imported links.
Compared with export links, the more import links, the better. Import links should follow two principles: breadth and quality. Quality comes first before quantity. Therefore, when we build incoming links, we must first pay attention to the quality of incoming links, and then pursue quantity. If you turn it upside down, not only will it not make the website friendly to search engines, but it will also make the website lose points in the eyes of search engines. Because when you pursue quantity, you usually forget about quality, resulting in too many junk links and invalid links. Therefore, the most important thing about incoming links is quality and breadth. Only when the two are well combined can the ranking weight of the website increase.
The above four points are summarized by analyzing the friendliness of the website to search engines. These four points are the author's experience gained from practice. I hope it can help you understand the website more or less. In turn, your website will be better included, have higher weight, updated snapshots, and better rankings.
