The theme should not be too scattered. The more concentrated the theme of the website, the more energy the website owner puts into this aspect, so the quality of the information provided will be higher.

2. Rich website content

The two complement each other, and the rich ones are usually welcomed by visitors. But the richness of content here does not mean the complexity of content, but the depth of content. When ranking websites, search engines should not only look at the information relevance of web pages, but also consider the reputation of websites, such as the number of external links, the click rate of web pages and so on. Therefore, websites with rich content will definitely rank in front of websites with poor content. Because different search engines have different web page support, we should not only pay attention to beauty when designing web pages. Many elements that are often used to design web pages will have problems when they reach search engines.

3. Frame structure

Some search engines (such as FAST) do not support frame structure, and their "spider" programs cannot read such web pages. Except AltaVista and Google, other engines do not support ImageMaps, and they explicitly support image block linking. When "spider" programs encounter this structure, they often feel at a loss. So try not to set the ImageMap link.

4. Special effects links

Many websites will add special effects to navigation links. For example, clicking an item will expand the links below. These effects are generally implemented in Java, which is visually novel, but not so attractive in the eyes of "spider" programs. On the contrary, it cannot explain this connection. In order to make search engines retrieve web pages smoothly, it is suggested to sacrifice some fancy things.

Step 5 flash

Although the visual effect of the webpage made by FLASH is very good, the search engine is not very interested in it. The case shows that this kind of website is difficult to be included in Baidu search engine. It is wise to provide FLASH and non-FLASH web pages, which not only increases the appreciation of web pages, but also takes care of the mood of search engines.

6. Dynamic Web pages

Anything with "?" The address number, "&"(and other similar symbols) will keep the "spider" program out of the door. These web pages are usually generated by CGI, PHP, ASP and other programs, which are advanced in technology, but not suitable for the "spider" programs of search engines. Although some large search engines (such as Google) have the ability to retrieve dynamic web pages, there are still quite a few number engines that do not support it. Moreover, even Google, which can index dynamic web pages, has made it clear on many occasions that it does not guarantee to retrieve all dynamic web pages.
