How can I increase my sales and find the right buyer? Here I have seen many who are successful. How ??
Who is your buyer? Get to know who is your typical buyer. In order to sucessful market yourself and your business you need to know where is your typical buyer, not only at Fiverr but elsewhere. This will give you a huge advantage when you share your gigs on Social Media, LinkedIn other places online. Good luck.
I really agree with @ligiacarvalho and you might try to send the buyer request because you can filter by your self the project that fits with your services
And you might build a strong profile metadata. You can mimic from some of your competitor mixes and match that. and periodically try and error the hidden metadata (my suggestion is on the weekend because the gig will inactive after changing the metadata)
