Start with the pages that combine high traffic with high intent: the homepage, top solution or use-case pages, and the pricing page. These pages usually sit on the critical path to demo requests and sales conversations, so even small improvements compound fastest here.
The homepage sets the first impression for every visitor segment. Solution pages are where prospects evaluate fit against their specific problem. And pricing is where qualified buyers self-select and decide whether to engage sales. Prioritising these pages means you're optimising the parts of the funnel that directly influence pipeline, rather than spreading effort across pages that don't drive commercial outcomes.
