website speed by Emarketing

With today’s high Internet connection rates webmasters don’t think they should bother much about their web page size and load time. Still this parameter remains essential both for SEO and usability:
According to eMarketer research 16% of people leave the page if it loads longer than 10 seconds and only every second person will wait more than 15 seconds (so you can lose half of your visitors by overlooking your page load time);
The general rule of thumb is to keep your page size up to 150K as pages greater than that are not fully cached by search engines (let’s put it like this: the longer a search crawler waits, the less it likes visiting your page).

Normally effected sizes on your website speed:

total page size;
total size of the images (and HTML and CSS images separately);
JavaScript size;
CSS size;
Each page object size;
And download times for a set of connection rates:

informative quality is the primary thing that we look for.but without speed that information too becomes kind of handicapped.net references are mainly preferred for their speed ...and speed is barred then it adds as a disadvantage

I agree with you, so the next time you will optimize your page try to consider the above list. I know some of us are trying to make our site look better but we never thought of things if it can harm our site or not.

Site speed is most important,otherwise no one will go to your site.
