Five towns, one website: deciding what yours should say
This is the question that comes up on nearly every Knowsley job, and getting it wrong is what leaves a decent business turning up for nothing. There are three situations and they want different answers.
You work from one town and most jobs are there. Say that town, clearly, near the top of the page, and say it first. A shop or a salon in Kirkby should read as a Kirkby business, with the borough mentioned once further down for anybody who searches that way. Trying to sound borough wide when your customers are all within two miles makes you vaguer to them and no more visible to anybody else.
You are a trade covering all of it. Name the towns properly, in a sentence a person would actually read, rather than hiding them in a list at the bottom. Huyton, Kirkby, Prescot, Whiston and Halewood written out once each is worth more than the word Knowsley repeated ten times, because the towns are what people type. Then set the service area on your Google Business Profile to match, because the profile and the site disagreeing is a common and quiet problem.
You sell to other businesses rather than the public. There is a fair amount of this around the business parks, and the rules change. Nobody is searching for you by town, so the location matters less and what you do matters more. Lead with the service and the proof, and treat the address as a credibility detail rather than the headline.
If you are not sure which of the three you are, that is worth ten minutes on the phone before anybody designs anything. It is the single decision that most affects whether the finished site brings you work.
