Agencies doing local SEO at scale, how are you handling location pages?

Most of my clients need 30-50 location pages targeting different cities. Same layout, different city/keyword on each one.

I've been doing this for years and it's still the most tedious part of the job. The actual SEO strategy takes an hour, then I spend the next two days building pages.

I've tried speeding it up with AI tools and custom scripts but honestly nothing has fully solved it. The content part is easy now, it's the formatting, internal linking, and actually getting it into WordPress that eats the time.

How are other agencies handling this? Anyone found a workflow that doesn't make you want to quit?
