The Overall Mark is calculated as
follows:

  • 36% weighting to Function diagnostics
  • 26% weighting to the Performance Mark
  • 20% weighting to the Accessibility Mark
  • 18% weighting to Quality diagnostics

Also, the following additions and subtractions are made:

  • If the "first page metadata" test is failed, 0.25 is subtracted.
  • For each of the Broadband and Fast Broadband "first page timings" tests, 0.1 is subtracted for each "fail".

Example overall Sitemorse Mark calculation

This is how an Overall Mark would be calculated for an example website.

Sitemorse Test Results Individual Mark Weighting
Function Diagnostics <0.040 problems per page 6/10 + 6 x 36% (2.16)
Quality Diagnostics < 7 problems per page 7/10 + 7 x 18% (1.26)
Performance <1,100ms
>= 270/sec 		7/10 + 7 x 26% (1.82)
Accessibility >=60% of pages pass A
>= 5% of pages pass AA 		4/10 + 4 x 20% (0.80)
Metadata First page FAIL   -0.25
Broadband Speed Test First page FAIL   -0.1
Fast Broadband Speed Test First page FAIL   -0.1
  Overall Sitemorse Mark: 6
