Great question. One way to get the word out is to partner with site owners who may be interested in partnering with you. See what you can do for them first to help cross promote. If you are selling, for example Christmas cards, you may want to partner with a site that sell Christmas cookies, or holiday jewelry.

You can also work out an agreement where you can buy space in a holiday website owner's newsletter. Usually this may not cost a lot, (it depends on how many subscribers they have) but this can get eyes on your site.

When people come to your site, you definitely want them to enter their email address so you can connect with them in the future. So ask them to sign up for your newsletter or maybe you will send them a free sample, etc. You just need a way to build your email list so you can share your products with them.

Create account on major social media sites. Facebook, Twitter, G+, YouTube, Pinterest, Instagram and post there. If you cannot spend money on advertising then you need to spend time on posting, sharing and interaction.

Hire some Virtual Assistant to help you in these areas.

Influencer marketing. Find a bunch of micro influencers with sub 5,000 follower counts on twitter, insta, fb, snapchat and offer to send them free product. Maybe throw in a referral link and pitch them on the commissions they can make.

The price being only your time to find them, communicate with them, your COGs, and shipping.

I grew my business in the first year by using subscription boxes for cross-marketing. The subscription boxes in my niche already have thousands of eager customers. The boxes source my product just above cost and we get to introduce ourselves to thousands of new potential customers. We don't have to pay; in fact, we generate revenue AND marketing opportunity this way. It's a win-win.
