Local SEO is the work that gets your business showing up when someone nearby searches for what you do. It's your Google Business Profile, your website, and how consistent your business details are across the web, all working together so Google trusts you enough to put you in front of the person searching.
Google weighs three things when it decides who shows up. Relevance is how well your profile and content match the search. Distance is how close you are to the person searching. Prominence is how well known and reviewed your business is. Most Brisbane business owners have never heard those three words, but they decide who gets the call and who doesn't.
This is different to regular SEO. Regular SEO chases rankings anywhere in the country. Local SEO is about winning the searches happening a few kilometres from your door, and that's where most service businesses get the bulk of their work.
