Generally speaking, after the website is built, website optimization work is very important. Website optimization mainly refers to website structure, page optimization, page design, page user browsing experience, website functions, keyword research, competition research, SEO effect monitoring and strategic improvement optimization. , Website optimization is mainly the release and construction of external links. One of the essential characteristics of a website is links. We can control the links inside the site, which is easier to grasp. But what impact do external links have on the SEO optimization of a website?
1. External links can increase the weight of the website
External links can increase the weight of the linked page and the entire website, improving page scores and trust. The more external links, the higher the weight of the website sending the link itself, which also indirectly indicates that the linked page is trusted by more people, and the weight and trust of the linked page will also accumulate on the entire domain name.
Website ranking is affected by website weight, but it is only an important factor in search engine ranking. Except for the size of the site. The quality and originality of the content of the article, the most important factor in forming the weight is the external link. Domain names with high authority drive the ranking of all pages on a website. Pages that link to high website links greatly reduce the likelihood of collecting content.
2. External links increase the trust of the website
Trust means whether your website content is all around the theme of the website. If your website links come from the heavy website links of Sohu.Sina.Tubatu.Tianya Forum, your website has a qualitative improvement. No matter what keywords your website does, ranking will be of great help.
3. External links can attract spiders to crawl websites
After building a good website, search engine spiders need to grab our website. If there are too few external links or even no external links, the possibility of spiders finding and grasping the website will be greatly reduced. After the website updates the article content, the search engine spider also needs to crawl the updated article content at the first time, including the article content page of the website. If you want to rank on a website, you must first include the content of the website production page. If the content of the website article is not included, we can publish the address of the website to some weight and trust websites in the form of an external chain, and the spider crawls to our updated content will be included, which is why the external chain can guide the spider Grab the website.
4. External links improve website page indexing
If a website wants to rank, the content of the website must first be included by search engines, so website page inclusion is the basis of ranking, and pages that are not included by search engines are not ranking. Experience in the data analysis and SEO industry shows that the quantity and quality of external links have a critical impact on website inclusion. Without the help of strong external links, it would be difficult to fully include our website just by relying on the internal structure of the website and the original content of the pages. An empirical number for reference is that a domain name of weight 5 can roughly push millions of pages, if there are too many, it is more difficult.
A link hierarchy view familiar to SEO practitioners is that internal pages must be within three or four clicks of the home page. The reason is that external links largely determine how deep a spider crawls. Generally speaking, for websites with lower authority, search engines can only crawl 3-4 layers of links. If a website has a weight of 7 or a weight of 8, search engines can also include content pages that are clicked 6 to 7 times from the homepage to improve the overall inclusion power of the website.
External links are also a very important factor that affects the frequency of search engine crawling. The more external links, the more frequently search engines crawl pages, and new pages and new content can be found faster. It is normal for high-authority websites to crawl the homepage every few minutes.
5. External links can improve keyword rankings
Search engines give a website a corresponding weight through the quality of the website's external links. For high-authority websites, keyword rankings naturally have a great advantage. Many new SEOs or webmasters believe that strong external links are the biggest guarantee of a website's ranking. In theory, a strong website external link can bring a good ranking to the website. However, the internal and external links produced by the website should also be gradually increased. Site rankings can only be stabilized if you find some add-on links on sites with high rankings on major search engines. In addition, through the maintenance of site groups by many experienced SEO drivers, friendship links still have a significant impact on website rankings. Webmasters can add two valuable friend chains every week, which indirectly improves website rankings.
6. External links can increase the exposure of brands and domain names
The release of plain text external links can effectively improve the exposure rate of website domain names and brands on the Internet, and help the smooth progress of network marketing. For some short and easy-to-remember domain names, it is also helpful for the promotion of website brands, such as: baidu.taobao.jd, etc., users can see what website, which is helpful for users to remember our website, which is conducive to the revisiting of the website.
7. External links can also bring traffic to the website
When SEOs publish articles related to their website topics on off-site platforms, they will bring their own links, which are likely to bring traffic to the website. If the value of this article is high, I believe it will not bring less traffic. The premise is that it can attract users to click, let the user know whether the link needs to be opened, so that the external chain can satisfy the user experience, and it is also a valuable link for the user.
8. Which is more important, the quality and quantity of external links?
Because today's Internet has too many spam links, if a website links redundant text, this situation is called a link factory, and search engines will also determine that the links sent by the website are spam links, so search engines will eventually tend to external links. quality rather than quantity. Many search engine optimizers often find that the number of external links on the competitor's website is not large, and the website ranking is also very good and relatively stable, so the quality of external links on the website is much higher than the quantity, and high-quality external links are better than dozens of spam external links .
