Banner ads and images on web page

how they make page heavier? do they effect the loading time of page?

[Navdeep]

i have seen and read many times that the number of big flashy banners and images make the web page heavier and effect the server response to load the page. is it realy true?
what should be the stratergy to get the banners and images on page with quick loading of page, at the same time?

do the different tools to develop banners and different formats of images makes any difference?

if images and banners do effect the page response time then,
if you use yahoo to send messages, after every
message you sent, you will notice a very big banner ad
at the right hand side. what is the density of such
banner?

Hi Navdeep,

It is very true that banners and images make a page heavier and do cause a longer load time than a plan text page.

The reason for this is all due to the ammount of information the server has to deliver to the users browser before they can see your full page.

If you think about this page. It is very graphicaly light so it loads pretty fast. Now if we had a masive banner at the top it we would also have to download that in order to view the page. The extra banner takes time so the page download time will be the time for the existing page plus the extra time for the banner.

You might want to think if it as downloading a file onto your computer.. the bigger the file the longer it will take to download.

You also asked why do Yahoo and other sites do it. They make money by selling the ad space. They probably have to weigh it up... do they make enough to justify the extra bandwidth and I guess they do.

Hope this is of some help.

thanks mack ,
so you think yahoo and others are using extra bandwidth to make this happen. could you please give me some idea about what bandwidth they must be using and what is a normal band width that most of the sites are using ,for data transfer.

and what about the image formats do different formats of images make any difference?

Hi again.

I woulden't even like to guess what yahoo use in terms of bandwidth...

Think of it as a bus. The bus company sell an advert on the side of the bus for $100 they then spend $50 to have a graphics company place the advert on it. Right away they have made $50. What yahoo do is a very simlar thing. They sell adverts and pay for the bandwidth.

Yes different formats do effect the size of graphics.

If you are using windows what you can do is go to a page with a graphic. Right click it and select save as.. save it somewhere on your computer where you will be able to easily find it. (my documents) then browse to that folder... right click the file and select properties. It will then tell you the file size of the image.

Again the bigger the file size the longer it will take to download and the more bandwidth it will use.

Hope this is of some help.
