I don’t know if you agree with “SEO, start with imitation!”? As an SEO, I quite agree. Why? When I first came into contact with it, I had never heard of knowledge. I could only bite the bullet and find different cases and tutorials to imitate every day. It took a long time to get to the walk and all in all it was a grueling time. The level is the same, but the transformation process from old bird to old bird is different. Maybe imitating this low-level method is also a way to learn SEO.
When I first started learning about nofollow, my first thought was limited to: using nofollow is an important weight-oriented method. Most of them place nofollow on various message boards and export links to control the loss of weight. I don’t know why I need to use nofollow? How to use nofollow? Until I exchanged links, the other party pointed out that I added nofollow to the “friendly links” of my site, and the exchange was directly rejected. I just came out of blind imitation and went to find out why nofollow should be added? Then I realized that in addition to controlling the loss of weight of various exported links, nofollow also plays a great role in optimizing the website structure. For example, it affects the spider's crawling, reduces ZZ's excessive repetitive crawling and crawling of the same page; prevents ZZ's crawling and crawling of unnecessary pages...
In the SEO learning process, the focus is on mastering skills and improving thinking. So how can we make good use of nofollow and carry it to the end?
First of all, master the two ways of applying Nofollow to pages: nofollow is a newly created tag led by Google in 2005. With its application on various well-known engines in the world, Baidu can now support this tag.
1. Write "nofollow" on the meta tag on the web page. The code format is: <meta name="robots" content="nofollow" />
This method tells search engines not to crawl all external and internal links on the web page, and prohibits following links on this page. Here nofollow: Tell the spider not to follow the links on this page. Such a page fully exposes the shortcomings of nofollow. Blocking all links on the page tracked by spiders (regardless of the impact of exported links) can also directly affect the depth of spider crawling in the site, which is not conducive to the ranking of long-tail keywords within the website pages. However, the specific application will be determined based on the actual situation.
2. Place "nofollow" in the hyperlink, code form: <a href="URL" rel="nofollow" >Text of anchor text</a>
This method tells search engines not to crawl a specific link, and only applies to this link. Compared with the disadvantages of the first method, this more targeted method is more conducive to optimizing the website structure by nofollowing specific links (which can be internal links or exported links). In terms of practical application, a comprehensive and detailed analysis of the website is required, and the final application is determined based on the theoretical and actual conditions of the website and combined with data analysis.
Thirdly, master the common uses of nofollow. The original purpose of nofollow is the impact of spam links on search engine rankings. The significance of the label is to tell search engines that the links added with nofollow are not edited by the webmaster themselves and are not trustworthy; they do not need to be tracked and crawled, and they should not be passed on. Weight and anchor text. The nofollow tag is usually used in the following aspects:
1. Text interaction. In order to increase user popularity, current websites usually have modules such as blog comments, forum posts, personal signatures, message boards, etc. for users to freely leave links in these places. The webmaster cannot find the link website corresponding to each link one by one, nor can he verify each link, which results in a large number of spam links and a large number of exported links, which seriously leads to the loss of weight. Today's mainstream blogs and forums have added nofollow to content and comments. For example, the NetEase blog added nofollow to all non-NetEase links in the blog post. This move also caused a lot of discussion among webmasters who value blogging.
SEOs all have their own personal blogs. You can try to set nofollow in these aspects, and you will get unexpected results.
2. Advertising links If the SEO's personal website has not reached a certain amount of visits, it will be difficult for advertisers to be willing to place ads, and it will also be difficult for advertising links to appear. The original intention of online advertising is to increase exposure and click traffic. Since the advertisement is also a link, it can also affect the weight and ranking. Adding nofollow to the ad link tells the search engine that this is an online ad, and there is no need to send spiders to crawl it, nor to pass on weight.
3. The incidence of duplicate links is very high and occurs on almost all websites. Today's website design is becoming more and more template-based. In large websites, corporate websites, WordPress blogs and other sites, the navigation bar of the website header and the footer at the bottom are common to the entire site and are links to the entire site. This situation will not only waste a lot of website weight, but also cause a large number of spiders to crawl and crawl repeatedly. For example, since the most common links at the bottom of the website are Contact Us, Privacy Policy, User Terms, Complaints and Suggestions, Talent Recruitment, etc., and users rarely care about such pages, obtaining rankings through search engines brings the possibility of traffic. Very low. Therefore, adding nofollow to these links appropriately is conducive to the accumulation of weight.
4. Pagination links Most of these links occur in blog sites and forum sites. Many websites have pagination pages such as 1, 2, 3, 4, and 5. Although these pages are very important, they are less important than the content in the pagination. It becomes negligible. Whether it is a blog site or a forum, content is the focus. How to give the few weight resources to the content. Adding nofollow to pagination can give the content the highest weight to the maximum extent. In short, use the nofollow tag flexibly and don’t let your website’s weight be wasted.
The above four points are of great reference significance for SEO whether operating large websites, corporate websites, or personal websites; it is helpful for SEO to master nofollow knowledge and to carry out nofollow to the end.
