Webmasters in the site after the SEO optimization, may be the entire site included in the analysis, often in this analysis process will find that the site classification directory below the page, and can not be fully included, this shows that the site optimization is not enough. So what are the reasons for this happening? Kedeng bloggers to give you analysis:
First: The website structure is not perfect. Many of the site's classification page will be due to the structure of the site, resulting in spiders can not smoothly crawl the main information of the site. General website structure is to use DIV+CSS positioning, the main content of the Web page on the layer, and the main site information placed in front of the code, such a method can improve the spiders crawl, and can allow the text to show. There is a cliché of the Web site title, as well as the keyword and description of the writing, these are seemingly simple but often the owners of the details of the questions, are the decision of your Web page will not be included in the problem, so in the analysis of the site is not sufficient, the first to understand the structure of the site is not perfect.
Second: The weight of the site is not high enough. The weight of the site is not high enough to update the new content of the site, spiders do not crawl, which is also causing the page included imperfect reasons. The weight of the site is not high enough, cause the weight is not high enough: the website server is unstable, the website outbound chain takes over, the website friend chain Influence, the website high weight outside chain is not steady, these external and intrinsic factors will cause the website weight not high enough. To solve the Web page can be fully included, may have to solve the site is not a high weight problem. My webmaster encyclopedia before the server is not stable, resulting in web site operation has been difficult, now changed the host, is on the right track. And the weight of the site is not a day or two can be improved, with the webmaster optimization means is a certain relationship, so the optimization should also be considered well, whether it is conducive to the weight of the increase.
Third: The distribution of the inner chain is uneven. A website may have many different page classifications, but the webmaster may not pay attention to the construction problem of the inside chain at ordinary times, this is very easy to lead to uneven inside the chain, site classification of the weight is not uniform, so spiders in the crawl site, may be a weight not high classification page crawl too little, this led to the inclusion of inadequate phenomenon. Such factors require webmasters to increase the construction of the inner chain. For large Web sites, may be more page classification, but the overall weight of the site is limited, it is necessary to find a reasonable allocation of site weights, improve the main classification of the chain, as far as possible to improve the main classification of the page included.
Four: The website page does not give the force. For some image sites, there may be a lot of flash in the site classification page, or some of the use of JS links, or the structure of the site there are a large number of problems, these factors will lead to the site page does not give force, will directly affect the search engine included, so natural also led to the page is not fully included. So the site to minimize JS code and Flash animation, this will not only affect your site's overall collection, but also affect the opening speed of your site, but also affect the user experience of your site, such a site jump rate will be higher. So it's important to optimize the site page.
Five: The quality of the website content is not high. In addition to the above objective factors, the biggest subjective factor may be due to the content of the page itself, many webmaster to add content to the site, and regardless of the quality of the content problem, directly to update. If the quality of the article is not high, the nature of spiders will be reduced, so the collection of the site is not sufficient. A large number of reproduced collection of other people's articles, will only reduce the weight of their own site, such things webmaster or do less good, have the time or to choose their own to original. This can really improve the collection of the site.
For the site will be long to run the webmaster, the regular analysis of the site's data, records of the site's collection, which is conducive to your overall understanding of the site, but also timely to help you find problems, you can also better solve the problem, the site can be a long-term operation down.
