HTML or HTML5

[sammiess]

I use only HTML5 for my websites. It's hard to work with internet explorer (they don's support all the functions of HTML5 and CSS3).

For SEO it's not a problem if you use or not HTML5 - here it's the content problem and linkbuilding.

you must learn adapting new techniques in order to become more successfull and compete with your rivals and for your survival in the market.

So you must go for HTML 5.

even google also loves new and advanced techniques.

HTML5 won't be released officially until 2015 last I heard, so during this stage, it will still be in beta mode and not all browsers will support it. This is why I'm still sticking to the regular HTML.

HTML5 is easy to learn. it made many works easy.
