Separate intent
Replacement windows, double glazing repairs and spare parts are different searches. Build a structure that makes these differences visible and use negative keywords where traffic does not match your offer.
Explain product and coverage
Use pages that describe the products you install and the areas you serve. Only display verified reviews and support energy-efficiency or savings claims with appropriate evidence.
Measure installation opportunities
Compare booked surveys, quoted projects and completed installations. Low CPL can be misleading if enquiries are consistently too small, outside your area or for unsupported products.
Put it into practice
Review one recent group of enquiries with your sales team. Agree the quality criteria, identify the largest recurring mismatch and decide what to change before buying more traffic.
