An external link is a link that is imported from another site to one of its own。
However, since the search engine gave high priority to the links, the links have changed completely and become a tool for the website to try to improve its ranking in the search engine. Google thinks it's a good site to be connected to. How could so many people like him? The more people like him, the higher it's pr, the greater the weight of the page. Links to other websites can lead to more visits。
Importing links is an important process for website optimization. The quality of the import link (i. E. The weight of the import link page) directly determines the weight of our website in the search engine. The effect of the outer chain is not just to increase the weight of the website, but also to increase the ranking of a keyword. A high-quality external link can bring good traffic to the site. Example: for any page a, any other site b, if page b is linked to page a, the link is a link to page a. Exterior chaining is an important process for website optimization, the quality of which directly determines the weight of our sites in the search engine。
Look at the robots. Txt file on the website and see if the page column you published in robots. Txt uses the disallow tag to shield the 100-degree spider. See if the site has been dynamically static. Despite the 100-degree dynamic pages, static pages have a much higher penetration rate than dynamic pages. Other organiser some sites appear to be linked, but are either viewed through the source file or displayed by the browser. See your link after the current website, which we call jump-links. For jump links, 100 degrees is not allowed to cross the link behind identification, so the link is invalid. Whether the link is js. This type of link is often a clickable link, but the source file is viewed or the browser displays javasCript code. The 100-degree spider can't yet recognize the link in the js code, so it's useless to make an outside link. The website uses the novollow label. The site is only available through the source file. The label is preceded by a novollow label, which will block the transmission of weights even if the current page is recorded at 100 degrees. However, in the case of the anchor text, such a site would not affect the true utility of the anchor text。
Methodology and role of the outer chain
An anchor text is a key word, a connection to a page, also known as an anchor text link. The anchor text can direct the search engine to the page to which he refers, the most desired expression. The ranking of keywords, the inclusion of article pages and the weight of the website are very helpful. Rational station anchor text can guide spiders to climb more pages, showing how friendly we are to the search engine. At the same time, the station anchor text provides good guidance in providing user experience. Users are often able to find the information they need accurately and quickly through anchoring texts, without which users tend to close pages。
The meaning of hyperlinks is the same as that of the anchor text, which points directly from one page to another, except that his expression is not a keyword, but a text-style link。
If there are many areas of interest to the site, it is clear that the site is widely distributed and well known. This effective domain is also an effective form of external chain if users who need it can access the site directly. It is not difficult to deduce that no anchor text has a significant impact on the ranking of hyperlinks and keywords, but the same effect on the weight of the website。
Plain text is a plain text, i. E. A link expression of a pure letter that cannot be accessed directly through another page. The role of a pure text link is the weakest in relation to an anchor text, a hyperlink。
But it's not that a plain text is useless. It's a plain text link that leads spiders, as we all know. However, a pure text, if properly applied, could make a large number of people willing to copy it, and could bring a great deal of traffic to the site. At this point, his role may be impossible to achieve by anchoring text and hyperlinks。
A photo link is used to make one link to another page. Pictures can be used to make alt properties, to facilitate the ability of spiders to recognize photographic information and to directly access the main points of the page。
Role:
Extra-chain resources can be obtained more simply by analysing the locations of our competitors; extra-chain resources can also be found by searching for the excavations of commands, such as those of inurl and initle; and extra-link resources can be increased by human connections, such as exchange with friends, exchange with internet users, etc。
