Why does the search engine not include webpages:
1. webpage framework: Content in the framework is generally not within the scope of Search Engine capture.
2. There are too many images and too few texts.
3. Submit the page to another website: the search engine may skip this page completely.
4. Submit too frequently: If you submit more than two times in a month, many search engines will not be able to handle it and think you are submitting garbage.
5. Website keyword density is too high: Unfortunately, the search engine does not explain how high the density is the limit. It is generally considered that the description of 100 words contains 3-4 keywords, which is the best.
6. text color is the same as background color: search engines think that you are building keywords to cheat it.
7. dynamic web page: The content management system of a website facilitates web page updates, but it brings troubles to most search engines. Many search engines do not charge dynamic pages or only the first page, will not be further charged. In this case, we should consider using the rewrite technology of the Web server to map the dynamic page url to a format similar to the static page url. If the search engine mistakenly thinks it is a static page, it will be charged.
8. Website Transfer Server: Generally, the search engine only recognizes IP addresses. When the host or domain name is switched, the IP/DNS address changes, and you need to submit the website again.
9. Free Website space: some search engines reject indexing websites from free spaces, complaining about a lot of spam and poor quality.
10. When a search engine crawls a website online: if the host is unstable, this may happen. What's worse, even if the website has already been indexed and is not online when it is crawled again, the entire website will be deleted.
11. mistakenly blocked the robots indexing Website: There are two ways to block robots: simple text files under the root directory of the host server; some meta tags are contained in the webpage.
12. A large number of web pages using flash, DHTML, cookies, JavaScript, Java, or passwords are difficult for search engines to extract content from such pages.
13. Search Engines cannot resolve your DNS: It takes 1-2 days for the new domain name to take effect after registration. Therefore, do not submit the website immediately after the domain name is registered.
14. website links are too broad: the links are too low and the search engine is hard to find you. In this case, you should consider logging on to a well-known category directory or making more links.
15. The server speed is too slow: the network bandwidth is small, the download speed of the webpage is too slow, or the webpage is too complex, which may cause the search engine to pause without searching for text content.
16. Keyword problem: if the text does not contain the keywords mentioned in your meta tag, the search engine may think it is a junk keyword.
