SEO framework iframe How to optimize
A frame or frame structure (frame) Web page behaves as if a piece of a Web page remains fixed, and other parts of the information can be moved up or down through the scroll bar. Another manifestation of frame-type Web pages is that the domain name of the deep page is usually not reflected in the URL, even if you go into the Deep sub page, the URL that the browser displays is still the URL of the homepage.
Its benefits are: The overall page is consistent, easy to update. But most search engines do not recognize the framework and are not interested in crawling the content. Some browsers do not support frames pages.
If you use frames, you must optimize them using the "Noframes" tag in your code, and treat the Noframe label as a home page for plain text content. Include a link to the frame page and descriptive text with a keyword in the <Noframe></Noframe> area. Keyword text also appears in areas outside the frame. This will make it possible for search engines to correctly index information within the framework.
Another option is to use an IFRAME, an inline frame (Inner frame) technique, to avoid the inconvenience caused by frame.
The so-called IFrame is also a form of the framework, which is equivalent to a child window embedded in the main browser window, the content automatically open. An Iframe can be embedded in any part of a Web page, optionally defined by its size, and its code is shown as: <iframe src=xx width=x height=x scrolling=xx frameborder=x></frame >
For search engines, the text in the IFrame is visible, and can be traced to the page to which the link points, but unlike what the user sees, the search engine will iframe
Content is viewed as a separate web-side content, independent of the embedded page.
