Skillfully use nofollow to exclude unnecessary links_Chang pin China focuses on high quality website construction

Website construction company Shangpin China: Website weight is an eternal topic for us SEOers, but how does this weight come from? Is it controllable? And how to transfer the weight to the desired page is the topic we will discuss with you today.

The explosion of the number of web pages on the Internet has given SEOer great development space and unprecedented challenges. Search engines should screen out high-quality pages from hundreds of millions of web pages not only based on the quality of articles, but also on people's recommendation of the web page (although it is no longer the main influencing factor). Links are not only external links but also internal links. Today, when the outer chain is unmanageable, web content cannot be accurately evaluated by search engines. What else can manipulate to affect the weight of websites? Yes, it's the inner chain!

Remember the sentence "content is king, and external chain is king"? In the old era of search engines, content is the most basic element of a website, and the outer chain is the highlight of a website. The appearance of PR value reflects that the weight of the article comes from the recognition of the article, so the quality of the article was not valued at that time, and the important thing is whether your article was viewed and topped. However, it violates the core value of search engines, that is, the relevance and practicality of website articles. Figures are very easy to cheat, so many websites previously gained high weight by buying external links and hanging black links, but what they brought to netizens was junk pages or advertising pages, which greatly hurt the user's experience. Therefore, search engines cracked down on external links cheating, gradually weakening the transmission of weight by external links.

A good internal chain structure should not lead to dead links. Secondly, all links have one and only one URL. Furthermore, you should not visit any other page from any page more than 3 times. Finally, nofollow is used to guide the search engine selectively.

When you think about it carefully, the inner chain has always been a link that early SEOers were familiar with but did not attach importance to. In the era when content is king, we know that the website should be flat, the directory should not be deep, and all pages of the website should be linked to form a network as far as possible. But how many Marketing website construction Can you do this? Let's start with dynamic website pages. One page has many different URLs. Which URL does the search engine crawl to when it comes in? Can you climb out after climbing in? Or can the weight stay on that page after climbing in? These are all issues to be considered by the internal chain. The mesh structure is not difficult to achieve. The simplest way is to make a website map and write all the links in it. But is this a good internal chain?

Finally, the great god nofollow was introduced. Eh? Why is it so familiar? Yes, it is an attribute added to links to prevent PR values from flowing out, which we learned several years ago. Can it also be used in the website? The answer is yes.

The search engine's response to nofollow is not to follow the link, that is, it will not crawl along the link, and of course it will not pass weight to the link. We learned when we contacted PR that the more imported links, the higher the PR will be, and the more exported links, the lower the PR will be. But power is not as simple as PR. The weight considers the current page article quality, the overall weight of the website, the weight of the source page import, the weight of the target page export, and the link relevance score and other factors. So don't be surprised that some websites still rank high with many exported links. So when should we use nofollow?

1. If you want to improve the ranking on the product page or topic page, you can release such links on the home page, and use nofollow for other links.

2. When there are too many links on the home page, we can use the nofollow tag to reduce some pages to share the weight of the home page.

3. Analyze the website log and set it according to the spider crawling situation. If the page that the spider often crawls is a column or page that does not have much effect, it can also be directly nofollow. For example, the sign in column of the forum is simply a column that has little effect. Such columns can be nofollowed directly, so that spiders have more time to grab other useful pages.

4. Unrelated links do not need to pass weight and ranking pages. For example, registration page, about us, contact information, etc.
