Hi Michelle, I think your backgrounds could use a little brightening up, since they are white, the same color as the back drop on every Etsy site, it becomes obvious that it's not a true white. Do you white balance? What types of editing do you do? I don't agree that they are over-exposed. If you're a photography self-learner, look up tutorials for your specific camera. Some photos outside with the items on a cutie might mix up your listing photos. I enjoy the listings that show just the fabric print - Ex) photo 4 here

People ask all the time where I get all my surfaces. It's just .99 paper from a craft store. I would suggest having a true white, a beige, a gray, and a black on hand and comparing with the print to see which is the most eye catching. Although, some customers really love the cohesiveness of having the same background on every listing. If you have a nice enough camera, I think having a super close up on every listing, to see the quality of the fabric, would be a lovely addition, and perhaps a packaging photo if you have packaging you're proud of. Some listings only have two photos, which lead my eye away quickly. I also would love to see an Etsy banner that is different from your shop photo, it is a little distracting. I love the way you arrange your photos, you definitely have an artistic eye. For SEO help, I use Maramead.com and just done quite a bit of research, and enjoy Rich Mom Business videos. Remember to use long-tail tags (3-4 words) rather than short-tail (2 word). Long-tail tags fare better in the SEO world. I would start my titles with a straight forward long-tail tag, such as, "Baby Bandana Bib" or "Baby Burp Cloth." The first words of the title are the most important. Hope this little ramble helps! Best of luck. Your work is just lovely. -Emily
