See a Sample Report (PDF)Most writing about duplicate content is about theft. That is rarely what hurts a local service business.
The version that costs you money is the one you built on purpose: a set of town or service pages generated from one template, where the only thing that changes is the place name.
Why it happens
The logic is sound. You serve fifteen towns. A page about each town should rank in that town. Writing fifteen genuinely different pages is slow, so you write one and swap the noun.
The result is fifteen pages that a search engine reads as one page repeated. It will usually pick one and largely ignore the rest, which means fourteen pages of effort producing nothing, and a site that looks thin in a category where thin is the norm.
There is no penalty in the punitive sense. The outcome is worse than a penalty because nothing tells you it happened.
How to tell if you have it
Open two of your town pages side by side and read them.
If you can swap the town names and neither page becomes wrong, they are the same page. That is the whole test, and it takes two minutes.
Three other places it shows up on service-business sites:
- Service pages that differ only in the service name. Drain cleaning and water heater installation are different jobs with different urgency, different price ranges and different questions. Pages that treat them as interchangeable read as interchangeable.
- A blog post republished as a service page, or the reverse, so two URLs compete for the same phrase.
- The same page reachable at several URLs. With and without a trailing slash, with and without www, with tracking parameters attached. This one is invisible and common.
What a real town page contains
Something that could only be true about that town.
- Work you have actually done there. Named streets or neighborhoods where you have permission, job types, what the housing stock is like.
- Conditions specific to the area. Older homes with particular plumbing, a water table, a soil type, a wind exposure, an HOA that requires certain materials.
- Reviews from people who live there. A review naming the town is worth more than a paragraph claiming you serve it.
- Coverage that is true. A page for a town you reach twice a year generates leads you turn down, and turned-down leads become the reviews that cost you the towns you do serve.
If you cannot write two genuinely local paragraphs about a town, you probably should not have a page for it yet. One strong page covering an area beats fifteen that say nothing.
The technical half
Pick one URL and stick to it. One protocol, one hostname, one trailing-slash convention, enforced by redirect rather than by hope.
Use canonical tags honestly. A canonical is a statement that this page is the same as that one. Pointing every town page at a single hub tells the search engine exactly what you were trying to hide.
Watch what the CMS generates. Tag archives, paginated category pages, print views and attachment pages create duplicates nobody asked for. Most platforms let you switch them off.
Check parameters. Campaign tracking on a landing page creates a second address for the same content unless handled.
Where to start
Count your town and service pages. Read any two at random. If swapping the names leaves both sentences true, you have the problem, and consolidating down to the pages you can genuinely make specific will do more than any amount of new content.
Fewer pages that are actually about something beats more pages that are about nothing. That is the entire lesson, and it is why this is worth an afternoon.
