For those of you that want to know . . .

Normally, calculators and other tools are provided to webmasters by means of an iFrame. An iFrame is a page of another website, structured into your web page like a picture is fitted into a frame.

In essence, the iFrame process is as follows: your server holds the code to create a frame page (i.e. page with logo, menu etc, but no content) for your website. It generates this page and displays it on your visitors’ computers along with an instruction telling your VISITORS COMPUTER to get the iFrame data (e.g. SunnyCALC™_LITE calculator). Almost instantly, the iFrame is found and loaded into the frame and the web page is complete.

Using our PHP include method (code above), the process is different: your server holds the code to create a frame page (i.e. page with logo, menu etc, but no content) for your website. It generates this page and also tells YOUR SERVER to get the iFrame data (e.g. SunnyCALC™_LITE calculator). Almost instantly, the iFrame is found and loaded into the frame and the web page is complete, and then the page is displayed.

To the casual observer, the result looks identical. However, in the first case, Google and other search engines see the instruction to get the external content, but in the second case they do not see the instruction because they cannot know what your served does before the page is displayed.

The search engines response in the first case case is to index the pages as being part of another website and improve the ranking of the other website. Furthermore, they PENALISE your website ranking for having copied content. Their response in the second is to index the pages as yours, and improve the ranking of YOUR website for having good content.

The reason why websites provide content to webmasters such as yourself using the iFrame method is clear – you promote their website. However, in reality they give you nothing other than the illusion that your website is improved.

The reason altereco.co.uk provide the SunnyCALC™_LITE tool via the PHP include method is that we include a link back to our website. The content we provide will improve your website ranking, and the link back to us will improve ours. We feel that this is fair split of the benefits, and will serve to motivate both of us to our mutual benefit.

Alternatively, if you do not need this tool, we would appreciate a link to us and we hope we can serve you in the furture.
