For large-scale company website is pretty much apply, but for a public website or blog is not so. Among the blogger who uses Blogspot, for example, is still rare that implement AMP. At least when compared to the blogger who uses WordPress.
HTML AMP technology offers that are not messing around, that extra speed between 15% to 85%. Or in other words, access a website or blog to 115% to 185% faster than before.
Among the things that may be the cause of this HTML AMP has not been much in demand are:
First, the fact that non-AMP technology is still very capable of satisfying or meeting the needs of the blogger or webmaster.
Secondly, perhaps many of the blogger or webmaster who feels reluctant to switch technology. Reluctant or unwillingness of the present without reason. Anyway, when it was offered to try AMP HTML they are reluctant, point.
Third, the reluctance or may arise due to technical issues. That is, when to dabble HTML AMP never managed during validation.
Especially for the blog platform Blogspot, modify or build a valid template AMP is difficult. All must be done manually script-by-script. Unlike the living Wordpress install plug-ins.
Fourth, it could be because the blogger or webmaster do not want to gamble. They are reluctant if later facts AMP HTML does not provide more value overall.
Fifth, the publication of which is less widespread. To this day kalamitra have never seen advertised HTML AMP project, for example.
Kalamitra found HTML AMP implementation is an investment. And an investment certainly has risks. If later AMP HTML is booming, so that's an advantage. But if the contrary so what can make.
