Two location or service pages must differ in their substantive, value-bearing content, not just a swapped city name or template variable, before they read as distinct pages rather than duplicates. The line sits at genuinely unique content versus a template with swapped tokens. If you stripped the proper nouns out and the two pages said the same thing, you have one page wearing two outfits, and a search engine will treat it that way.

Changing the city name and a few words is not enough, even though it feels like work. The reason is that the words carrying meaning are still identical, the same generic claims, the same boilerplate process, the same stock reassurances. Surface swaps move the labels around without changing what the page actually offers a reader. A page about plumbing in Austin and a page about plumbing in Dallas that differ only in the city and a couple of adjectives are, in substance, the same page twice.

What makes them genuinely different is content that could only belong to that one page. For a location page, that means real local detail: the neighborhoods you serve, regional conditions that affect the work, local pricing realities, specifics tied to that place. For a service page, it means the distinct specifics of that service, its real process, the actual problems it solves, examples and cases that apply to it and not to the others. The differentiation lives in the parts a competitor could not copy by find-and-replace.

For your next pair of pages, run the swap test before publishing. Cover the city or service name with your hand and ask whether the remaining content still uniquely describes this page. If it could describe the other one just as well, you have not differentiated them yet. Give each page substantive content that is true of it alone, real local detail or genuine service specifics, so that what remains after the proper nouns is itself distinct.
