I messed around a little with WML back in 2002.
There were several problems back then - not least the unpredictable
capabilities (especially storage capacities) of the available WAP
clients and the sheer cost of browsing at mobile phone rates.
My phone accepts RS-MMC cards - 1GB now costs GBP16. Most phones
currently shipping have cameras or MP3 players and consequently huge
storage capacities. Many contract phones include free minutes and GPRS
is threatening to become affordable.
So I'm revisiting the idea. Google is gently ramming Mobile Sitemaps
down my throat at every opportunity and I must admit there are more WML
than HTML-capable platforms out there. It's just that absolutely no
one uses them.
I'm putting a trial site up. Does anyone have any recent experience of
the relevance of
SEO to mobile sites? The obvious stuff doesn't work -
there are no meta tags, no description, and you simply cannot include
vast amounts of text. Do search engines index WML pages at the deck or
card level?
Capacity of current browser platforms? I'm doing most of my testing on
a Siemens S65 - but my experience four years ago was that browser
capabilty was both extremely critical and extremely variable. I've got
some HUGE files to load into its browser, but it can be very slow (tens
of seconds) to do quite simple things like a BACK request. Odd
behaviour - instant display of the start of the target page but a
delayed return to the original jumping-off point.
It strikes me as odd. There's no public evidence that anyone is doing
anything at all with WAP - yet there is a limited opportunity already
and 3G technologies _could_ lead to an explosion.
I'm aware of

lacks
SEO perspectives.
