I get traffic to many of my symbol domains, some of them relatively lots of traffic. (over 100)
I see using them this way. say you have:
www.âtravelâ.com (one of mine)
Someone types the word "travel" into google, and this domain comes up in the results because you've done what you need to do to get it optimized enough to do well in a search. (like all web owners aspire to do)
If someone sees this domain, surrounded by all the normal domains, which will they click on? Everyone will be curious to see what this airplane symbol travel domain is, it's unique, interesting, a curiosity, very unusual, cool, etc. So they'll click on it, and then you can redirect them to your travel site. You will get a LOT more traffic on your site using a symbol domain of this kind as a redirect. All the other travel domains look the same when they come up in results.
OR if this will BE your travel site, and you've done a good job with it, the viewer will bookmark the site, and then they don't have to have the airplane symbol on their keyboard. They just go to their bookmarks/favorites.
Those are the two ways I see as using symbols. That's why I actually think symbols work better with a word in them. This way they'll show up in searches when people type in that word. And it's the surrounding, interesting-looking symbol that will guarantee their click.
I'm not sure how to get a plain symbol (like
just the airplane) to show up in a Google search. That's why most of mine have a word in them. Though I did buy some plain ones because they are interesting and a novelty. And I've gotten quite a few bids on them.
