We've done a lot of stuff this spring to prepare for the fall, because I know from experience that promoting events with only a few weeks notice is not going to be as effective. So we've been working the marketing plan and adjusting as we go along.
One of the things we did was a Circle of Friends promotion, where clients sent the contact info for 25 of their friends who have not used us yet but who THEY think would be interested ("25 of your friends just like you who you think would love our work.") The existing clients got a complimentary session and an 8x10, but with a deadline (pre holiday rush) to get people in early. The 25 friends were offered a complimentary session and a 5x7 from their friend, expecting that maybe 1 out of each set would take us up on it. Again, with a deadline to book. We've added over 350 new local names to our database (we did have a few of the new contacts opt out), that are more pre-qualified than buying a mailing list because they have an in-person testimonial built in.

I do not expect to do a
ton of the complimentary sessions, because of my price point and the time of year, but it has introduced me to a good number of potential new clients. That promo deadline was mid-July and we've booked seven sessions off of it. So far the three that we've photographed have spent just above our average, even with the gift print.
I also have a couple of partnerships going on, and we have some joint hs senior "events" planned for early fall (which I'd rather not talk about here till it's over, because this is a fairly public board). I've run three different specials, that were not discounted, but offered something that I don't normally offer in the studio for a limited time... so we've done press releases and email (and some printed) mailings for all those.
And then one of the most difficult strategies, because it takes some extra time and thought and planning every day, is that I am on a mission to blog at least four times a week, because that generates so much word of mouth. I have only been doing this for about a month, but it's driven site traffic way up and everyone who has called to book for the last couple of weeks has mentioned "well we've been following your blog...". So we'll give it a few more months to see how much power that really has. It seems to be helping with search engine optimization

because of all those keywords and the frequently updated content.
