Looking for report to convince C-level management to invest in site speed improvements

i'm trying to convince C-level managers to spend more resources on improving the website speed, because my feeling/hypothesis is the current performance (avg page loadtimes often >5sec) is bad for conversion rates.

 

i need to come up with proof, and quantify the revenue loss due to high page load times.

 

what report(s) would you suggest is create/use?

 

i've been looking at a custom report that lists avg page load times and conversion rates for 'day of month', 'month of year' dimensions, metrics: sessions, avg page load times, ecommerce conversion rate.

However, for 3 big ecommerce sites i see no correlation...

 

thanks already.

Hi Boeli,

 

First of all, If you are using GA for the site speed data, make sure that your data collection is adequate.  By default only 1 percent of hits get sampled for speed insights and up to 10,000 hits can be sent a day.  So if you are getting less than 1MM pageviews you should set your sample rate higher.

Once you have enough data collection you could plot speed vs conversion rate.

 

Secondly, yes, slow sites cost conversions.  Google did a study recently:

thanks!

 

does increasing the sample rate in GA tracker have any negative impact on the page load times on my site?

Hi Boeli,

 

No, it just means that it will send site speed data more often in hits.

 

Best.
