For an ad with one offer
For an ad about one service, let the page continue the same promise: who it is for, what is included, the price or pricing approach, relevant examples and one contact action. Too many unrelated links can distract a first-time visitor.
For multiple services and deeper consideration
If your business offers different services, give each a useful page and include work and an explanation of your process. Customers get room to compare, and each URL has a clear search topic. Repeating a page with only the city name changed adds little value.
Start with what you need now
Launch suits testing one focused offer. Business suits most companies that need services, work, an introduction and contact. You can expand when there is content or a clear reason to add more pages.
Mobile is the clarity test
Open the ad’s link on your phone: is the offer understandable without zooming, is the button clear, and is there enough information before the action? Heavy imagery or a long introduction can delay the information that matters.
