I work on Google Business Profiles for realtors and local businesses every day, and I keep seeing the same 3 mistakes that cost them calls.
1. Wrong or missing business category. If Google does not know what you do, it will not show you for the searches that matter. Fix: pick the category that matches your main service, then add the rest as additional services.
2. No photos, or only old photos. A profile with no recent photos looks closed or out of business. Fix: add 3 to 5 real photos of your work, your team, or your office, and add a new one every week.
3. No reviews, or reviews with no replies. People read reviews before they call, and an unanswered review looks like nobody is home. Fix: ask every happy customer for a review, and reply to each one within a day, even the short ones.

The meta keywords habit really never died, some plugins still push that field. A unique title and a meta description written to earn the click do so much more.
