There are many places on the internet today to advertise or spread the word about your photography business. If you have a headshot business in San Antonio you’ll want to focus on getting the attention of locals. Yes, not the rest of the world but local citizens of San Antonio and the areas within 10 miles outside the city limits. Advertising to everyone not in your community will not benefit your business.
Places on the web like Tumblr are a good start to expand your reach or web presence. You post local photos from San Antonio and still have potential clients seeing your photography work. If you add your web link and contact information you should get some traffic from there to your regular website.
We hope this little bit of information was helpful to you.
