I still remember that when I learned the iframe tag, I thought it was not very useful. Then I met it again in a place some time ago, and it was actually related to SEO. After a detailed understanding, it is true that the ifram tag has disadvantages in SEO. favorable!
First let us understand what is an iframe tag?
After using the ifram tag in a web page, a new document frame will be created in the location of the web page. For example, ifram is used in a certain location in web page A to call an exception web page B, this will display in the frame called by A that the page called in web page A is called. part. How to use:
<ifram><img src=”url of webpage B” > or the content of this article from other webpages can be written inside the tag. Now let’s go back to SEO and see what are the disadvantages and advantages of using this tag in the website. .
1. Search engine spiders will not recognize the images, texts, URLs and other content called in the ifram, because the content does not belong to the page and is only temporarily called when accessing, and it is also mentioned in the SEO recommendations: "The frame/frameset/iframe tag will make it difficult for Baidu spider to crawl, and it is recommended not to use it." This further proves its disadvantages!
2. From its disadvantages, we can think of the exception of the commonly used tag nofollow in HTML. Since using the iframe tag can make it difficult for spiders to crawl this part, then we can show some of the needs of our website to users without The information seen by search engines needs to be designed using ifram tags, so that ifram can turn waste into treasure and have the effect of slimming down the code. For example, such as the filing information, honorary certificates, certifications, etc. on the homepages of some large websites. We don’t need to show these links to search engines, because this dilutes the weight of the homepage of the website. We can use it with ifram, and it only needs to be used on the homepage. Other pages do not need this information. Isn’t it very Perfection, this is its benefit!
Although using ifram tags has its benefits, it is not better to use more ifram tags in the page, because using a large number of ifram tags will dilute the keyword density of your page and have an impact on it. Search engines may also think that you are is cheating, so website optimizers recommend not to use it too much
Although it is a small label, the SEO knowledge in it can still be tossed in. Well, that’s it for today’s introduction to Hubei SEO. I will continue to share it next time!
