Does the proposal show they looked at your business?
It should. A proposal worth reading opens with findings about your company: your Google Business Profile, your website, your reviews against the companies you lose jobs to, and the towns and services you want more work in. If it opens with what SEO is, or a package price with no findings, it was written before anyone looked.
A quick test: cover your company name and read the first page. If it could describe any contractor in any city, it's a template.
For a home-service business, the findings should cover at least:
- Your Business Profile: missing services or areas, wrong categories or hours, unanswered reviews.
- Your website: whether each main service and town has its own page, and whether visitors can call or request an estimate from a phone.
- Your reviews: how many you get and how recent they are, compared with the companies that show above you.
- Tracking: whether calls and form requests are counted at all.
If the agency offers an audit before you sign, Google has advice on access: "only grant read access to Search Console (at this stage, don't grant them write access)."
