This starts with an unexpected discovery today. The company has several websites. There are links between each other in the friend chain. I just changed a link and wanted to check it. When I checked it with the webmaster tool, I found that it didn’t have my own link! It turns out that I put the friend link in footer.hmtl. Then embed it into the homepage through iframe. In this way, what is detected is not the home page link, but the link to the footer page. The same goes for search engines. Search engines will look at the pages introduced by iframes and follow the links inside, but they don't pay that much attention. And each separate iframe is also processed as a separate page. In fact, this can be found when viewing the source code of the page. You can only see the code of the iframe, but not the code of the page inside.
Code
< div id="foot" class="clear_left">
frameborder=" 0" hspace="0" scrolling="no" vspace="0"
allowtransparency="1">
Based on the consideration of these issues. There are many places where iframe cannot be used. Although sometimes it is very useful.
iframe is no longer intentionally used. Of course find a way to replace it. The first thing that comes to mind is of course include, and there are many types of include. As far as jsp is concerned, there are two types: one is the include instruction %@include file=""%>, and the other is the jsp action instruction:
By the way, I found that Tencent’s website does not use iframe. It is used by many other big websites, such as Sina, Taobao, etc. Looking forward to knowing the solution for qq.
