Too small a change
At 2,000 visitors a month a different button colour is not measurable. Test whole pages, not details.
B2B and leadsIndustry
B2B sites have few visitors, but every enquiry counts. That changes what you test.
The gain comes from more than one source, not from a single campaign.
The pattern
At 2,000 visitors a month a different button colour is not measurable. Test whole pages, not details.
The deal closes months later. As a primary goal you need something that happens often enough within the test window.
Three more enquiries in week one are chance, not a result.
Concretely
As a redirect test. Goal: form submission.
A starting price or project range. Goal: qualified enquiry.
Two routes to a conversation. Goal: booked appointment.
Social proof before the service description. Goal: form submission.
Measuring
Use the form submission or the booked appointment as the main goal. Plan honestly: with little traffic a test often takes six weeks rather than two.
