Suggestions from GOOGLE website to website administrators

Website administrator guide
Follow the guidelines below to help Google search for, retrieve, and rank your website, which is the best way to ensure that your website is listed in Google search results. Even if you choose not to accept these suggestions, we strongly recommend
Pay close attention to the quality guide, which provides a brief description of some prohibited behaviors that can cause websites to be permanently deleted from Google indexes. After the website is deleted, the search results of Google.com or all Google's partner websites will not be displayed.
Website design and content guide:
The website should have a clear hierarchy and text links. Each webpage should be accessible through at least one static text link.
Provides users with a website map and lists links to important locations of the website. If there are more than 100 links on a website map, you 'd better split the website map into multiple webpages.
The website should be practical and informative, and the webpage text should be clear and accurate.
Consider the keywords that the user will use to search for your webpage and ensure that the website contains the text.
Try to use text instead of images to display important names, content, or links. Because Google Crawler cannot recognize the text contained in an image.
Make sure that the TITLE and ALT markup words are clear and relevant to the webpage content.
Check whether the link is damaged and whether the HTML format is correct.
If dynamic web pages are used (that is, the URL contains "? Note that not every search engine Spider can include dynamic webpages as easily as static webpages. Shortening the parameter length and reducing the number of parameters will help to include dynamic web pages.
Limit the number of links on each webpage to a reasonable range (less than 100 ).
Technical Guide:
Because most search engines use the same way as text browsers, you can use text browsers such as Lynx to check your website. If complex technologies such as Javascript, Cookie, Session ID's, frames (framework), DHTML, or Flash are used, all webpages of the website cannot be viewed in a text browser, the search engine Spider may encounter problems when indexing your website.
Allows the search bot to include your website, and does not use Session ID or other parameters to track its browsing path. These tracking technologies are useful for understanding the behavior of individual users. However, because the access modes of the roaming server are completely different, using these technologies may lead to incomplete retrieval of websites, because the roaming bot may not be able to exclude the URLs that seem different but actually point to the same web page.
Make sure that your network server supports the If-Modified-Since HTTP header. With this feature, Google can know whether your website content has changed since the last time it was recorded, which can save your bandwidth and expenses.
Use the robots.txt file on the network server. This file will tell the Crawler which directories can be charged. Make sure that the file content is updated to avoid unexpected interruptions to the indexing of Googlebot crawlers.
