Because of different search engines in the Web page support differences, so in the design of the Web page should not only pay attention to the appearance of beautiful, many of the usual design pages often used elements to the search engine there will be problems. Frame structure (frame sets)
Some search engines (such as fast) do not support frame structures, and their "spider" programs cannot read such pages.
Image block (image maps)
In addition to AltaVista, Google and Northern Light (now discontinued public Search service) explicitly support image block links, other engines do not support it. When a "spider" Program encounters this structure, it often feels dazed and bewildered. So try not to set the image map link.
Special Effects Link
We often see some websites that add special effects to navigation links, such as clicking on an item to expand the underlying link. These effects are typically implemented in Java script, which is visually novel, but not so tempting in the eyes of the "spider" Program, instead of interpreting the link. In order to let search engine smoothly search your webpage, suggest or sacrifice some fancy thing.
FLASH
Although the flash production of Web page visual effect is better, but the search engine is not too cold, the case shows that this kind of site is difficult to be Baidu search engine index. It is advisable to provide both flash and non-flash Web pages, which adds to the viewing of the Web page, and takes care of the search engine sentiment.
Dynamic pages
Any address with "? "Number," & "(and other similar symbols) of the page will be the" spider "Program block outside the door. These web pages are usually generated by CGI, PHP, ASP and other programs, technologically advanced, but not suitable for search engine "spider" Program. While some large-scale search engines, such as Google, already have the ability to retrieve dynamic Web pages, quite a few of the engines still don't support it. And even Google, which is able to index dynamic Web pages, makes it clear on multiple occasions that it is not guaranteed to retrieve all dynamic pages.
Therefore, unless it is a very large site, for the sake of convenience has to use Dynamic Web page generation technology, or try to use static Web pages as well.
Encrypt Web pages
Do not encrypt your pages unless you do not want search engines to retrieve your pages.
Web page capacity
Web pages, including images, should not be more than 50K in number of bytes. The large page download speed is slow, not only will let ordinary visitors wait for impatience, and sometimes make "spider" Program feel impatient.
Standalone domain and paid virtual hosting
Currently, search engines are reluctant to include websites that are located on free home space. The reason is that since you think your site is so important that you need to log in to a search engine to make it known to everyone in the world, there's no reason to put it on a free server. What's more, free homepage is usually slow, which can affect the efficiency of searching information.
Of course, there are exceptions, if your site is really good, it may be accepted by the search engine, but under the circumstances, your ranking will always be with those who have a separate domain name behind the site.
