Hello, I've got following question, if some webmaster insert iframe with my site (webmaster component) into his website, so do I have any SEO advantages? I think isn't, but i ask just in case.
Generally i use readfile() and css, but many guys have blogs without css and php and have to use iframe, but if iframe has no value for googlebot, so why i should offer webmaster components in iframe.
OK, so if (for example) blog like wordpress.org does not support PHP, what is alternative for iframe and SEO/googlebot friendly?
Contents of iframes generally do not get indexed by simply being on another page which is indexed. Consider an iframe like a hole with unknown contents (to the se). Unless a link points to what is inside the iframe, it does not get much/any se recognition. SEs do frown on iframes - especially if they have ads in them. If someone jams your site into an ifram on their site, they could potentially be wasting a lot of your bandwidth (because your server is filling the frame) without giving you full advantage in terms of content visibility. If they make a tiny little box that still costs you the same to "show", it's not a good thing when the person looking into the iframe hardly sees your site at all.
iframes are fine, they don't cause penalization. The url you use in the iframe doesn't get indexed in google and there is no pr loss so don't worry about that. But if you want to pass pr, just post a link in addition to the iframe and then you've solved that problem.
It's all depended on you and the environment where you wanna use it. As far as I know, now a day, Google is crawling IFRAME pages but Google will show it separately. The contents of IFRAME page and the page where the IFRAME is placed have no any relation which their contents and any other. Suppose, I've created a page named PAGE1.HTML and have putted a health related article. And, I'm also displaying another health related article page named PAGE2.HTML within the PAGE1.HTML page through IFRAME. User can read both the pages PAGE1 AND PAGE2 by browser environment but Google will find only PAGE1.HTML contents. They will too crawl the PAGE2 also but the contents between them are not combined by Google. So the Google will read those two pages separately (a) http://yourdomain.com/page1.html and (b) http://yourdomain.com/page2.html Google will show your IFRAME page also whether you've any link to your IFRAME page or not.
