Many times when we do foreign trade websites, we will create a news column. The purpose of using news is to increase the update of dynamic information on the website. This can continuously add content to the website and arrange keywords in the process of adding content. This optimization is good.
Because the foreign trade websites of different companies have different positioning, the categories of news will also be different. For example, some have a "PRODUCTS INFORMATION" section in the news, and some add a "KNOWLEDGE" section.
No matter which section is added, in terms of content layout, news, as a first-level category, is first crawled by Google. After crawling, the articles inside will be extracted for in-depth crawling.
However, in order to avoid too many repeated crawls, such as "PRODUCTS INFORMATION" and "KNOWLEDGE", the articles here have been crawled in "news". If Google crawls "PRODUCTS INFORMATION" and "KNOWLEDGE" here, The "KNOWLEDGE" page will repeatedly crawl the list articles in it.
For better optimization, we can learn from the noindex tag given by Google and edit it, so as to tell the Google search engine not to crawl the secondary category list page.
The noindex tag is written as follows:
It is to add a piece of code like this at the beginning of the page to inform the Google search engine, so that Google will recognize it when crawling and skip the page without crawling or including it.
As shown in the picture above, the tag page using noindex must not be placed in the website site map, otherwise Google Search Console will report an error.
