Should I built a microsite for client's new service or add a new section to an existing new website?

[escteam]

We built a new website for one of our clients. Covering services A B C mostly commercial and industrial B2B construction service. We bought him a brand new domain called serviceAcompanyname.com The website uses a brand new domain and as no DA and PA yet.

The client wants a new section added to the Website concerning a new service ( we are going to call it service D) which is still a local service but offered to Home owners.

Should we buy a new domain called serviceD-region-companyname.com and make a microsite covering the topic and work on backlinks and links in parallel for both sites, or would we be better off just adding a new section to the existing website and work on the main DA.

Will it be easier in the future to enhance 2 different domains or a single one even though all services are not targeting the same audience.

escteam,

By the looks of  the domain you bought and put the new site on, I'm wondering whether the client still has an old site on an old domain and the one you built is in addition to that one.  If that's the case, then the client already has two sites and you're asking  about building a third.  Unless the primary domain has been penalized or there is a good non-seo reason to set up a new domain, it's usually best to focus on a single domain.  Time spent on building authority will positively impact most/all sections of the single domain, where twice the time will be necessary to achieve like authority if services are set up on two domains. Keyword rich domain names are kind of an old-school thing and I wouldn't waste any time considering them these days.

Exact match/partial match TLDs have been losing weight for a while now. They're still somewhat important, but is it important enough to fragment your efforts? The hyphenated stuff should be right out, especially for what you're considering.

Without knowing the main site you're working on, I can say that you should focus on one property. If you were a general, would you rather commit your resources to two fronts, or one? It sounds like you would head down the road of constantly new domains. Don't do that.

That approach is a disadvantage for both your client and yourself. Not only would there be diminishing returns on your efforts, there would be diminishing returns from The Googles algorithm. It sounds like you're going to have to fight the decreasing weight of a partial match or exact match domain to begin with.

Focus on one property. Make a new section. You will probably save on development time. No one on the face of the planet saves on content time.
