It is well known that only pages that are captured and recorded by the search engine spiders are likely to compete for the results, so how to establish a relationship between the site and the search engine spiders is a matter of greatest concern to station chiefs。
The search engine spider (also known as web spiders, web reptiles) uses extremely sophisticated capture strategies to reach as many sites as possible across the internet, and also captures more valuable resources in a comprehensive way that ensures that the experience of the users of the site is unaffected. Large search engines send large numbers of spiders on a daily basis, starting with websites with a higher weight or with high access to servers。
The search engine spiders are able to access more web pages along the internal and external chain entrances and store the information on the web pages in the database. As in the case of libraries, different books are sorted, and finally compressed and encrypted into hard disks that can be read by themselves for searchers. The internet we search for is the database。
In terms of the principles of spider capture in the search engine, the ceo of seo should, in order to develop the web site regularly, do the following:
Regular updates of high-quality website articles
First of all, the search engine spider likes to grab a regular website. In a sense, the frequency of website updates is proportional to the frequency of capture. Even though there are no spiders to retrieve articles in the early stages of the website, they are regularly updated. This allows spiders to access and measure the patterns of updates to the site and to regularly undertake new content captures so that the site articles can be updated and captured as quickly as possible。
Second, original and fresher articles are easier to capture by spiders. The presence of a large number of repetitive content on the site can make spiders feel too many to make sense, and can make the search engine question the quality of the site and even lead to penalties. The “fresh level” refers primarily to the extent and effectiveness of content, and the new “mass events” and “hot events” are relatively easy for users to notice and capture by spiders。
In addition to these two points, the distribution of keywords has important implications for spider capture. Because one of the key elements in the search engine's resolution of page content is keywords, but the stacking of too many keywords is considered by the search engine to be “cheaping”, the distribution of keywords should be controlled at a density of around 2 to 8 per cent。
Ii. Ensuring server stability
The stability of the server is not only a matter of the user experience of the site, but also has a significant impact on spider capture. Station chiefs should regularly check the server's status, check website logs, check for markings such as the 500 status code, and identify any potential hazards in a timely manner。
If the website is confronted with hacker attacks, website bugs and server hardware breakdowns, and the failure of the server for more than 12 hours, the closed-site protection of the 100-degree platform should be activated immediately to prevent 100-degree miscalculation of the site's invalid and dead-chain pages, and the site and server should be repaired in a timely manner。
Long-term unstable servers can lead to the inability of spiders to effectively climb pages and reduce the homogeneity of search engines, resulting in lower intakes and lower rankings. So the website has to choose a stable server。
Iii. Optimizing the structure of the website
If the site is good, the pages are small. Most of the time, because the pages were not even crawled by spiders. The site should then be thoroughly tested, including, inter alia, the robots file, the page level, the code structure, and links to the website。
1, robots document, full name of the “web reptile exclusion criteria” (robots exchange protocol). The website can tell spiders which pages are accessible and which pages are not。
2 page level, expressed in the physical level structure of the website, logical level structure, etc. Using the logical hierarchy of urls, for example, easy memory, short hierarchy, and static urls of moderate length are popular with search engine spiders. The url structure (marked as “/”) is generally inappropriate for more than four layers and is too complex to facilitate the recording of search engines and to affect user experience。
3. The type and structure of website codes can also affect whether web pages are captured by spiders. For example: ifRame, javasCodes such as cript, which cannot be effectively understood and captured by the spiders of the 100-degree search engine, need to be minimized. In addition, too large a volume of code can lead to incomplete spider capture。
The number and quality of web links, which are the “entry points” for inter-page weights, directly affect the ability of pages to be captured and recorded by spiders. Low-quality web-link piles can only bring devastating disasters to the site, and they need to eliminate false and dead links in a timely manner and reduce spider capture times of dead links. As many inverse links as possible from formal and related sites would increase the weight of the website。
In addition, websites can provide some shortcuts for spiders, such as sitemap. A well-structured web map allows the search engine spiders to understand the structure of the site and thus capture the entire page。
Through high-quality content updates, high-quality links exchanges and a rational web structure, the search engine spiders can better understand the site and capture the page. However, some pages that do not relate to the content of the website should not be published or over-optimized to attract spider capture. Because only a website that is truly committed and can bring value to users can be liked by search engines and users。
