Common causes of failure to log on to the search engine:
1. Framework:
The content in the framework is usually not within the search engine's capture range.
2. Too many images and too few texts
3. Submit the page to another website
The search engine may skip this page completely.
4. Too many submissions
5. Website keyword density is too high
Unfortunately, the search engine does not explain how high the density is the limit.
6. Text color is the same as background color
Search engines mistakenly think that you are building keywords to cheat it
7. Dynamic webpage
The website content management system facilitates web page updates, but it brings troubles to most search engines.
8. Website Transfer Server
The search engine generally only recognizes IP addresses. When the host or domain name is switched, the IP/DNS address changes, meaning you have to submit the website again.
9. The webpage does not have an independent IP address
Some host vendors allocate the same IP address to multiple users to save money. As long as the search engine blocks one of the websites, all the websites under this IP address will be affected.
10. Free website space
Some search engines reject indexing websites from free spaces and complain a lot about spam and poor quality.
11. Websites are not online when search engines crawl
This situation may occur if the host is unstable. 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.
12. 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 included in the webpage (for details, see Ping Wensong robots.txt and Robots META tags)
13. Use Flash, DHTML, cookies, javascript, and Java to create or use passwords to access webpages.
14. Search engines cannot resolve your DNS
It takes 2-4 days for the new domain name to take effect after registration. Therefore, do not submit the website immediately after the domain name is registered.
15. Website links are too broad
16. The website URL contains special characters
Such as: &, $, =, % ,? These characters are usually contained in dynamic web pages. We recommend that you add a parameter such as "www.site.com/articles/query.asp? Article = 83"
17. The server speed is too slow
Webpage download speed is too slow, or the webpage is too complex, it may cause the search engine to pause without searching for text content.
18. Keyword problems
If the text does not contain the keywords mentioned in your META tag, the search engine may mistakenly think it is junk.
19. Wait.
According to a survey by NEC, many search engines index a website for up to half a year.
Common causes of failure to log on to the search engine Directory:
1. You have not logged on to the correct category directory.
2. The website lacks relevant content.
3. The website looks unprofessional and too amateur
4. The website requires a special plug-in or password to access
5. The traffic is too low to be welcomed
6. The website does not provide a postal address that is untrusted.
