SEO website optimization search spider like what kind of website?

To put it bluntly, a web spider is a program that has its own characteristics. We should study how to do it according to its characteristics Beijing website construction Promotion, how to cater to his taste to attract it, so your Beijing website production The promotion method should conform to the taste of spiders. They will collect and take away their favorite online food one by one and send it to the base camp (database) for storage. Your information can be searched out from the base camp. I learned a few points about the crawling characteristics of web spiders. Now I will introduce how to deal with this web spider.

Spider taste 1, take the heavy and discard the light, like the new and dislike the old

When updating the collected website data, the spider does not crawl the entire website page again, but judges the update date of the website and compares it with the last crawl. If the date is not updated, it will not ignore it.

As mentioned earlier, spiders like shallow crawling. For websites with different weights and PR values, the frequency and depth of crawling are different. This has its own calculation method. Websites with high weight may crawl once every few hours or even minutes, while those with low weight may not visit once every few days or even half a month. For the crawling depth, for example, if the weight of your website is 2, the crawling depth will only go to the first or second layer of links. For the third and fourth layers, it will not be ignored.

Spider Taste II, prefer static rather than dynamic

Dynamic websites are pages generated by programs, which are relatively simple to maintain, do not need professionals to operate, and are highly interactive, which is also the reason for the growing number of dynamic websites. But this will bring some trouble to the spider's crawling. Compared with the dynamic, because the static web page does not have a database, the spider will directly crawl information on the page, and it is difficult to deal with the dynamic web pages generated by some scripting languages. Especially for some websites of sales nature, product upload should constantly generate new pages. The development trend of the website has a great contradiction with the preference of spiders.

The voice of spiders, when building a website, should make a static page of the website's characteristics, important content and fixed information, such as company profile, and contact us. For pages that often need to publish product information and constantly update website content, we can convert them into pseudo static pages irregularly through corresponding technologies.

Spider taste 3, do not like deep diving

According to the statistical data, the largest search engine database only captures about 40% of the entire Internet web pages. The biggest reason is to avoid the excessive data volume, which affects the search efficiency. Therefore, according to its own "habits", spiders only capture those important web pages, and its judgment is based on the depth of web links, First, it will grab all the pages linked to the original page, and then select one of the linked pages to continue to grab. Of course, it will not stop grabbing. It believes that shallow links are high-quality pages, which also conforms to our habit of thinking about problems, and always puts the important things first.

Spiders' aspiration, when building websites or choosing web templates, should do shallow links, not deep links. Spiders don't like to dive too deep.

Spider's aspiration is to constantly update the website content, so that the spider can take more fresh data to the database. If you want spiders to climb deeper, you need to work hard and do everything possible to improve the website weight and PR value, so that spiders can come more frequently. In this way, the ranking of websites in a virtuous circle will naturally rise.
