Speed Speed Speed - A Walmart case study

I know you know how important speed is right?

But do you really know?

Do you really understand the link between page load speed and conversions?

Walmart investigated and here are some of the results.

And it showed a huge link between load speed and conversion rates.



And also a big link between bounce rate and page speed



Here is the post with the detail

they have to be concerned bout that stuff because they've got a big site, lots of graphics and content.

we're doing shit on a much smaller scale... 1 offer.... 1 site.

just make sure its coded by a pro for speed and you're all set. its not much of an issue unless you've got a big ass site like they do.

True, but page size isn't everything. Check your ping stats when running high traffic and you'll be surprised how fast your server goes down the shitter, especially when you're tracking your visitors.
Even when you're running a 20kb small text site, your tracking software will have to track it.

Agree ibanez!

And dconstrukt - if your sending 100k views to a landing page per day it might have 1 offer and be 1 site but the loadspeed is still crucial.

Those that do a ton of PPV are used to this, but those doing other types of traffic often dont think about this.

Besides page 'size', you need to consider:

* redirect speed if your using a tracker that uses redirects
* dns/nameservers
* load balancing / caching
* webserver setup (ie concurrent number of users that can be served at ones)

common solutions are:

* server side caching (apc, varnish, etc)
* CDNs
* reducing page size (as you suggest)

How can you test your load speed and such?

This was a great reminder. I took 15 minutes and increased the load time of an LP from 2.78 secs to 978ms. All I did was convert my jpg and gif images to gifs with as low a collor palette as possible.

caching left and right, varnish, apc, memcached big way to make the server or vps able to handle more traffic faster way

i use blitz.io


http://blitz.io/fb5axJT

yes thats aff link, but all i get is an extra 25 concurrencies (users per second) for each signup

with blitz io you can simulate loadtime of upto 250 visits per second in 60 seconds (ie it will go from 1 per second to 250 per second over a 60 second period)

Crazy but it makes sense. My attention span is exactly four seconds.

Here's another infographic, posted today on RWW, about the affect page load has on visitors:
