SEO and technology is closely related, many people think that do not need to do SEO technology, in fact, this is a misunderstanding, if you do not understand the technology, it is impossible to do a very successful SEO, out of the problem can not make scientific decisions, in many people's eyes, SEO is nothing more than a day to send some articles, send some outside the chain so, If you also understand SEO, that means your level is still in a very early stage, even if the search engine is a technology is very strong things, then, we want to get the corresponding flow on it, we must have some technology, at least we should understand its principle, Then in the site's page to meet the technical requirements of SEO, we should pay attention to what problems?

1. Use a text browser to check your Web page to see if the important URL link in the page can be crawled by the text browser

The commonly used text browser is lynx, you can install it in the Linux environment, it in the browser your Web page, almost with the search engine spiders see the content of the same, so we often use it to test the Web page can be crawled, if your page important links using JS, Ajax and other technologies, Lynx browsers do not see these links, and the same search engines cannot capture them. Therefore, before the site online, you can use a text browser to check the main page, to see if the use of the search engine unfriendly technology

2. Allows search engine spiders to crawl your site without using session IDs or parameters that track their site access path

Some session IDs are useful for tracking the user's access behavior, but they are not good for search engines, and if you use these techniques, your Web pages may be indexed incomplete because search engine programs cannot rule out the differences from URLs. But the page content is exactly the same page. For the inclusion is not friendly.

3. Ensure that your network server supports if-modified-since HTTP headers

If your server supports If-modified-since-http headers, when the search engine spider program crawls to your Web page, it will first check this if-modified-since HTTP header value, through this value, Search Engine crawler can judge your Web page since it last crawled, whether there have been changes, if there is no change, it can not download the same page content, save spider resources, but also save your server bandwidth, so that spiders can crawl more other pages.

4. Set up a reasonable file for robots

Each site is best to set up a robots file, if your site does not have any content do not want to be indexed by the search engine, then you can create an empty to the name of the file, the directory uploaded to the root of your site, through the robots file, we can let the search engine crawl certain directories, But do not crawl some directories, such as some template files, you can prohibit the search engine crawl, some backstage login files can also be used to prohibit the use of a file, in the setting of the file, must be careful to avoid some important documents to prohibit, We can use Google Webmaster tools to test.

5, the site for compatibility testing to ensure that in each browser can be correctly displayed

Before we were online, it is best to do a large number of browsing experiments, to ensure that the content of the Web page can be correctly displayed in all browsers above, such as IE has an IE tool test, you can test each IE version of the display effect, Google Browser has similar plug-ins, you can test the compatibility of the browser, After testing can be normal display, and then on-line, in peacetime maintenance, you can often go to test the compatibility of the page display

6, often use some front-end test tools to test the performance of the Web page

For example, we can use Google's page speed tools and Yahoo's YSlow to test the performance of the Web page, these two tools can also point to the page in your site need to improve the place, we can follow the steps described in the front-end page optimization, such as enabling gzip, Enable keep-alive, use CSS sprites technology, merge JS and CSS, etc. The above content by Chinese beauty talent net www.mrrencai.com in Admin5, reprint please keep the URL, thank you!
