Is it an individual resource causing the problem?
The Process• Determine the pages that matter most to conversions.
• Define the areas that need the most improvement within those page groups.
• Make sure those areas matter.
• Examine 3rd party resources (if there are a lot).
• Look at the spread of different resource domains to determine who is the
problem.
• Load time histogram of the bad guy.
• Find out if the problem is with one resource or if its bad all over.
• Take action with these results!
Thank you!
