Hi Md Ashifur,
No, the feature is still in testing and it's not available to all freelancers at the moment. In the future we may roll it out to all users.
The feature idea is great. It's realy useful to see if some of the existing or potential customers checking your profile and it allows me to evaluate how my profile fits to market. The problem is that it is slightly buggy and does not provide sufficient information.
In my "Who viewed your profile" list I can see 3 viewers but those viewers are not changing for last 100 days. Other customers are grouped in "others also viewed your profile" section and does not provide any information.
Linked in has similar feature but it is used for upsell. If you want to see complete list of viewers you can buy premium status and get it.
On upwork there is no way to see the complete list and take actions.
I think that it would be good if freelancer will be able to see all the customers who visited profile. It will allow to check which projects do they have, how the current profile fits to it and what could prevented customer from invitation after checking profile. It would allow to market myself better.
It would be fine even if this will be paid option or part of freelancer plus status.
