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!
