Google Business Profile is the control panel for your business listing on Google. When someone searches for your service plus a location—say "accountant Ottawa"—Google shows a Map Pack with three local businesses. Your GBP is what populates that listing with your address, phone number, website, hours, photos, and review score. Without it, you're invisible in local search. The profile lives at business.google.com and syncs across Google Search, Maps, and even the Knowledge Panel that appears for branded searches. You verify ownership (usually by postcard, phone, or email), then fill out every field Google gives you: primary category, service areas if you're mobile, attributes like "wheelchair accessible" or "free Wi-Fi", and a business description up to 750 characters. The description doesn't directly rank you, but it clarifies what you do when searchers land on your profile. Google uses three core signals to rank GBP listings: relevance (how well your categories and description match the query), distance (proximity to the searcher), and prominence (review quantity, rating, citation consistency, and overall online authority). You can't change distance, but you control the other two. That means picking the right primary category—don't use "Marketing Agency" if you're really an "SEO Agency"—and building reviews systematically. At Ottawa SEO we treat GBP as the foundation of local visibility, not an afterthought. We upload high-res photos monthly, post Google Updates weekly (mini-blog posts that show activity), respond to every review within 24 hours, and ensure the NAP (name, address, phone) matches citations across directories like Yelp and Yellow Pages. Inconsistent NAP data confuses Google and tanks rankings. One watch-out: GBP suspensions happen when Google thinks you're violating guidelines—keyword-stuffed business names ("Ottawa SEO Inc | Best SEO Agency Ottawa"), virtual offices in industries that require a physical location, or serving areas you don't actually cover. If suspended, reinstatement takes weeks and requires clean documentation. Keep your profile compliant from day one.
