What GBP posts actually do for rankings
GBP posts are a freshness and activity signal — they tell Google your profile is actively maintained by the owner, which correlates with map-pack stability. They are not a direct ranking factor in the way that reviews, categories, or proximity are. The mechanism is indirect: profiles posting weekly hold rankings through algorithm updates better than dormant profiles, and posts earn occasional click-throughs and 'view profile' actions that feed prominence signals.
Don't expect a 3-spot jump from posting. Do expect to lose ground if you go dark for 60+ days.
Posting frequency: what actually works
Minimum cadence: 1 post per week. Optimal: 2–3 posts per week. Diminishing returns above 5/week — posting daily doesn't outperform 3/week in any A/B we've seen.
What matters more than raw frequency is consistency. A profile posting once a week for 12 months will hold rankings better than a profile that posted 4 times a week for 2 months and then went silent.
Post types and the mix that works
Use a rotation across the four GBP post types:
- Update — project photos, team news, seasonal tips, weather-related service notes. Workhorse type, 60% of your mix.
- Offer — actual seasonal offers (spring tune-up special, fall maintenance package). 20% of your mix. Tag with start/end dates.
- Event — open house, charity event, workshop. 10% of your mix when relevant.
- Product — for service businesses, treat 'services' as products. 10% of your mix highlighting individual service offerings.
What to actually post each week
The single most underused post format for East Bay service businesses: a photo from yesterday's job with 2–3 sentences of context including the city name. ('Replaced a 15-year-old water heater in Walnut Creek yesterday — homeowner caught it before it leaked.')
These posts hit four signals at once: freshness, photo authenticity, city relevance, and service-category relevance. Ship 1–2 of these per week and add 1 seasonal/offer/tip post and you're at the optimal cadence with content that takes 10 minutes per post.
What not to post
Skip generic 'inspirational quote' posts, holiday GIFs, third-party stock images, and pure self-promotion without context. They don't engage, don't signal anything useful to Google, and dilute the quality of your posting history.
