AJAX is not the page view killer some would suggest. It will suffer the same fate as Flash, and Google will be holding the smoking gun.
AJAX is the latest and greatest thing since sliced bread. It’s going to change the way we surf the web if you believe the hype.
I personally love it. The problem is search engines don’t and when I say search engines, I mean search engine. If you actually take a step back and look at the landscape, you will see it is Google who is in charge of deciding how we develop our websites. They tell us what other ads we can use if we want to run adsense. They dictate what links we must place nofollow tags on to stay within their guidelines. Their algorithm determines how we should link our sites if we want proper link weight distribution to obtain rankings. Google for the most part controls the flow of traffic and revenue on the web.
