You have to try different things, and when you find something that works, repeat it. Another thing I do is look at all of the popular Gigs and copy the keywords. I then use some of those keywords on all of my Gigs, whether they are related or not.
This will increase your views, and keep your Gig on the first 3 pages.
After the Gig falls back past the 4th or 5th page, your orders will drop off.
Another tactic is to set up the same Gig numerous times, just reword it. For example, I've found four Gigs that were popular that I could copy, and set them up 5 times each, wording them differently.
I get on the average 8-10 orders every day with this method.
Now, for high demand Gigs. They are:
- graphics, headers, ebook covers, anything photoshop
- seo, linkbuilding
- traffic
- social media
- web design, squeeze pages
- article writing, press releases
That's where I get most of my orders. I've also done well by getting a bunch of MRR squeeze page packs and Wordpress themes, HTML templates, etc, and selling them in a bundle as a Gig.
Had one of those Gigs that got 11 orders in one day a couple of weeks ago.
So, Fiverr isn't bad if you know how to work it.
