The first thing I immediately notice is that all of your gigs are based around writing. That’s fine, but Fiverr tends to throttle the amount of traffic going to gigs that share a lot of key words since they’re wise to people trying to manipulate the algorithm. (Speaking about the people who create gigs like “will create amazing logo,” “will create professional logo,” “will create beautiful logo,” etc.)
Instead of having four gigs as you do now, I would narrow it down to two gigs that offer a wider scope of writing-based services. (Example: Two gigs that read as “I will write x, y, and z” and “I will create a professional business plan” respectively so you can stop tripping the throttle algorithm.) You stand to lose traffic for about 24 hours while the new changes take effect, but optimization counts for a lot when trying to make sales.
It’s also worth noting that we’re getting into the summer now. People tend to be off on their vacations with their families, so less business-oriented things are taking place.
If nothing else, it’s the perfect time to optimize and be patient.
