Search engine ranking algorithm rule: Image ALT attribute text is no longer valid
In webpage design, the ALT label of an image is used to describe the image name and so on. Many keywords of ALT tags play a role in search engine optimization and are often used to increase the keyword density of webpages, therefore, adding theme-related keywords to ALT is a factor in search engine optimization. However, according to a long-term test study conducted by the SEO research sites WebMarketingNow and Search Engine Academy in the United States, currently, the three major Search engines Google and Yahoo! And MSN search engine ranking algorithm rules no longer use text information in the ALT attribute of the image as an effective factor for determining the relevance of web content.
The researchers said that in the past six months, we found that the image is intentionally filled with a large number of ALT keyword texts, not only does not help the search engine ranking of web pages, instead, the ranking results will be affected due to the suspicion of ALT Text Spam. Obviously, search engines are reluctant to break the user's search experience by simply improving the search result ranking of websites.
An engineer at Google clearly stated: "The content of the ALT tag should be related to the image content. Correct descriptions of the image content will give the user a good experience. The ALT tag content can indeed be indexed by the spider program, but the weight level in the ranking algorithm is further reduced ."
The purpose of the ALT attribute is that when the image cannot be normally displayed for some reason, webpage visitors can also determine the content of the image through the attribute text, it originally meant that the user could understand the webpage information correctly, not the search engine. Under normal circumstances, if the ALT attribute has one or two keywords, the problem can be explained. If you set too many words for search engine retrieval, SPAM is a problem. Given that many SEO applications that use ALT properties deviate from their original meaning, it is also reasonable that search engines no longer use it as a factor for webpage content relevance analysis.
According to the website optimization idea of the new competitive network marketing management consultant, website optimization aims at obtaining better information for users, rather than obtaining a good ranking in search engines, A good search result ranking is only a natural manifestation of normal website optimization results, rather than a deliberate target. Other elements of webpage design, such as Webpage title, META tag content, and webpage subject content, should follow the user-oriented principle. ALT attribute descriptions of images should also return to the origin: briefly describe the image content. Whether or not the rank algorithm of the search engine considers the information in the ALT attribute, you must also correctly set the ALT attribute description of the image from the user's perspective.
