Always be marketing because practice is what makes you better.
“I have not failed. I’ve just found 10,000 ways that won’t work.” -Thomas Edison
When you speak to your customers, find ways to genuinely use “keywords” to promote your business and draw in your customer. In your marketing material (flyers, door hangers, e-mails, business cards, even your clothing) be sure to utilize words and phrases that draw in your intended customer. Change it up periodically too; try not to get stuck and utilize just one thing that you may have found to work. Experiment a little - instead of buying 5,000 or 10,000 of one mailer or door hanger, try a few with one message and see how well it did - then try a few with a slightly different message or graphics and see which one does best.
Always be practicing.
