I completely agree with the fact that most of the advice you receive from other sellers is based on their personal experiences, as Fiverr do not disclose much about their algorithms. However, based on my own experience as a freelancer, I can say that having multiple clients inquiring about your services within a short period of time is generally a good sign. It shows that your gig or profile is attracting attention, and people are interested in working with you.
Even if these clients did not end up placing an order, it does not necessarily mean that your profile will be negatively affected. Fiverr's algorithm takes into account various factors such as your response time, reviews, completion rate, and overall activity on the platform to determine your ranking in search results. As long as you continue to maintain a good response rate and provide quality service to your clients, you should not have to worry about any negative impact on your profile.
That being said, it's important to keep in mind that Fiverr's algorithm is constantly evolving, and there may be certain factors that could affect your profile ranking in the future. Therefore, it's important to stay up to date with the platform's policies and best practices to ensure the continued success of your freelancing career.
