I found something:
-some of my ads are acting strange, at something like every 10-15 pageload, one of the ad is responding very slowly, i 'll test with it and see what happens
Also i have two other questions:
1.) Delayed loading of page:
Some part of my site(pictures, and ADS) is loading based on the browser:
These parts only appear once you really scrolled to that part of the page (made by an ajax script) So how does google measure these parts when it's calculating page speed.
2.)Goole Analytics script:
In google analytics bounce rate and visitor time of a page is false. But there is a script which triggers google analytics, and since i put this script(about 3 days ago) My bounce rate is really low, and page visit length is about 4 times like it was. But because of this script , there is a never-ending pageload, cause it loads GA every now and then. Does this affect the measured page speed? (I've just put this script on my site, so the WMT page speed problem isn't because of this.)
