You shared your gig and nobody bought your service. That alone should tell you that either your service is not good enough or your shared it with wrong people.
Why are you going to Facebook anyway? There are thousands of buyers here that are interested in translation service. All you need to do is convince them that you’re one of the best.
And let’s say you find people from FB, they come here and see that there are way more established sellers here. Why should they pick you?
OK so let look at your gigs.
Your EN > FR translation gig
Does your cover photo explain what you do and why should buyers choose you? I’m checking your competitors that are using videos where they speak French. I would pick them.
Is your gig description really reflecting your experience, value and proof that you can translate from EN>FR?
I have a good experience in translation and writing in some languages like English, French and Arabic.
Is this the best you can do as a writer? Good experience in some languages?
When I check your competitors I can see actual certifications, published work & samples. I would pick them.
All we know you might not speak French at all
There’s no proof. No video, no samples in portfolio, nothing.
Joking aside, you’re competing with sellers that have put much more effort into their gig. They have spent some time reading this forum and learned how to sell their service. With the gigs you have right now it doesn’t really matter where you promote it, your competition is doing much better job.
