How do I build an SEO strategy for a construction law attorney without wasting months on the wrong things?

We have tried nearly every SEO approach we could find optimized Google Business Profile, consistent blog publishing around construction disputes and contract law, directory listings, and attorney bio pages built for E-E-A-T and yet after nearly two years we still cannot figure out which efforts are actually moving the needle and which ones are just consuming time we do not have. The frustrating part is that some of our most basic content occasionally brings in a consultation while our most detailed and carefully optimized pages on mechanic's liens and contractor liability produce nothing. That disconnect makes it impossible to know where our real leverage is.

We do not know what to prioritize:

• Are our construction law practice area pages the foundation that everything else should support or are they actually the problem?
• Is our local content specific enough to compete or are we still too broad to rank for anything meaningful in the construction law space?
• How much content does a two-attorney construction law practice actually need to build enough authority to convert without burning out on production?

At this point we are trying to cover every base subcontractor disputes, bid protests, construction defect claims, delay damages, lien waivers without any clear structure for deciding what matters versus what is just noise.

To those who have actually figured out SEO for construction law attorneys without an expensive agency, what does your content strategy actually look like and how do you decide what to produce versus what to cut entirely?
