Hi Ak and Hamse Bashe,
Thank you for your messages. Results vary depending on the type of profile used to conduct the search since a number of factors are taken into account. Clients may get different search results for the same keywords and filters than freelancers using the same parameters.
Your search ranking may vary since a number of factors are taken into account but I assure you that the search feature is working as designed. In addition, freelancer profiles are regularly rotated in search results in order to give everybody a fair chance of being discovered by clients.
