Focus on a specific niche or at least create multiple gigs targeted at a specific audience.
For example, when I’m looking for a VO gig for a screencast narration then I search for “narration voiceover”. I get about 50+ gigs and I start going through the samples.
Your gig won’t show up because even though you probably offer narration VO, your gig is not optimized for that niche. The same goes for animation VO.
Go to search and type in “animation voiceover”. Does your gig show up?
If it doesn’t and it’s your strength then create a gig for it.
Another thing that has an effect on me is the VO artist’s personality. What makes your gig stand out?
Out of the 4 gigs below, I would probably pick the most expensive option because it’s unique.
Ask yourself, do you wish to appeal to an audience that chooses based on the price or do you wish to attract customers who are looking for something unique? If the latter then make your gig stand out
