The website construction company summarizes the reasons why the new website is not included

　 1. Update frequency (the frequency is too low, and the number of spider grabs is too small)

2. Website structure (too deep, too many dynamic parameters, and the robots. txt returned by the http protocol status code 301200404 is non-standard)

3. Website content (empty frame, empty column, a large number of duplicate pages, garbage pages, illegal information)

4. No external chain was introduced or drained.

5. Domain name problem (domain name is not clean, in short, it has been done in industries that are not conducive to SEO or illegal)

6. Frequently modify the title (so Baidu doesn't know what type and theme your website is)

7. Server problems (no ip, no UA, no spider)

Update frequency: content updates should make spiders form the habit of regular visits. It is not feasible to catch fish in three days and update the net in two days. Even if you send 100 articles a day, it will be considered as plagiarism, because you cannot create so much content after changing a new site.

Website structure: the structure should be flat. It is better not to use a tree directory structure of more than three levels for new websites. The best is the domain name+column page+details page. Do a good job of navigating the 404 error page to prevent spiders and crawlers from crawling because robots. txt is incorrectly written.

The following content problems will never occur: such as empty boxes, empty columns, a large number of duplicate pages, garbage pages, illegal information, and frequent changes in website programs and website theme types. The first second is the information station about flowers and plants, and the second is the information station about electrical appliances. How do spiders judge your website?

Outer chain: I didn't submit the website to the search engine on the webmaster platform, because at the beginning, there were few outer chains and no drainage, so it was difficult to attract spiders to climb. At this time, we should do more drainage and create high-quality original articles.

Domain name problem: Domain name has been used, its predecessor is gray industry or violates national laws.

Often change the title: many new webmasters change the title too frequently, the content changes too much, and the theme is unclear. You need to determine the core keywords of the website in advance and figure out what to do. When you are building an external chain, you can properly use keywords to make friendship links for the website.

Server problems: Many are caused by the server's response time being too long, the website cannot be opened when spiders crawl, or the website takes too long to open, and even some small servers often have problems. So you should choose a reputable space provider, such as Alibaba Cloud, to purchase servers.
