I actually think they're listed by who fits the customer's criteria the best. I still get listed for customers that have a lower budget than what I charge for my services, but I'm listed lower than those that are a better match based on availability and budget. However, I am curious as to what other criteria is considered choosing the order of listings.
2. Promoting your business
@Wreach I looked into your account and there are a few things that I can recommend to you in order to rank higher when a customer is searching for a pro. First, I'd expand on your profile a little bit more by getting some more recent reviews and completing your FAQ section. Next, I'd really encourage you to promote your business. When you promote your business, you tell us what jobs you always want! From there, we connect you with customers and they can reach out to you the second they’re interested. Plus, you also get a rank boost and will appear higher in search results. This video here will give you a greater understanding of Promote, check it out!
@CLGPatrick yes they hold equal weight, however, it can depend on your competition. For example, if you and the other photography pros in your area all have a solid profile, great reviews, respond quickly, but you're the only one who promotes your service and has pricing set up, then you'll show up higher. Let me know if you have any other questions, I'm happy to clarify!
