We are often on the site when the same content appears on the page, such as company profile and so on, these things are very long, will reduce the original degree of the page, the similarity is too high, not very friendly to SE. At this point we can consider writing this part of the content as a separate simple page and then invoking it through an IFRAME.
A chestnut, http://www.mjeyes.com/special/fm/page, the middle of the blue bottom of the text often appear, then we directly call
<style= "Border:none;" src = "http://www.mjeyes.com/fm.html" width = "100%" Height = "1155px" frameborder = "0" scrolling = "No" ></ iframe >
We add some original content AB before and after this IFRAME, the crawler will not crawl the IFRAME, only crawl AB, so the overall quality of the page content will be relatively good.
There are also some sites to improve the user experience, the use of double navigation or multi-navigation, then they put these small navigation into the IFrame form is also a good practice. From this point of view, is it possible to take all the bottom footer to the IFRAME call?
