Did you work hard to get a professional logo done for your client? After you have sent him the logo, you can still use the files to your advantage. You should submit your best logos to sites that accept submissions. Not only will you get valuable feedback from other designers and visitors, but may also find potential clients with almost no hassle.
Furthermore, these sites are also great for link building, as they allow you to post your designer link. This way you can get easy backlinks for quality websites.
Some websites accept your logos instantly, whereas others will review them first. Either way there is a very good chance on getting accepted if you have a nice looking logo. The only think you should keep in mind, is that almost all websites require another format for the logos. But with photoshop and similar software you can do that in seconds.
