I truly feel for the masses of logo designers who try to sell logos online. You can see the enormous amount of time that each (well, most) invested in building their logo design sites. Months of building and rebuilding and refining – for what? For a site that won’t work.
Before you build your logo design site, look through existing logo design sites. There are thousands. Look at their depressing Alexa rank too. My estimate, based on the Alexa numbers, is that most of those sites attract between 30 and 100 visitors per day (Alexa rank 1,000,000+), which probably translates to 2 or 3 sales per month.
If you are serious about selling logos online, you will need a plan. You need to get people on your site. If you don’t have a plan yet, sell your logos at LogoGround until you do. Put up a basic one-pager site in the meantime, but don’t spend months building an awesome web site that no-one will visit.
