EX_S > So I'm wondering, for those who put such a message in NOFRAMES, are they turning away more than just the 1% who can't view frames?
Yes I think almost certainly they are.
For example I for one usually don't bother to visit such sites out of disgust for bad frames implementation.
I think immediately .... huh they have not taken the effort to ensure that a description showing in search engines is indicative of their content .... well that is probably an indication of how little effort they have put in on my "their intended user's" behalf.
BTW for me the same goes for
"best viewed in xyz" messages ..
1. It is possible to have a framed site where a decent description appears in search engines.
2. It is not that hard to make framed sites contain a fully working non framed version which users of non framed browsers can visit and navigate without realising that there is a framed alternative.
3. It is possible to make a framed site perform better in many search engines than a non framed site.
4. if the site is created using static html without any server side includes it is often easier to maintain / upate a large site using a framed rather than non framed layout.
So why would it be that folk like that had not made the effort to implement any of these yet persist to use frames ... ?
Well it indicates that they did not make much of an effort.
