Everything is very simple. Each company has its own rules, but in general they are similar. For clarity, usually the bounty manager himself gives an example of how to properly do a report. Also, by browsing the topic, you can see examples, just like other bounty companies do. Mainly follow the deadlines for submitting reports. Here is an example of a report in the facebook bounty:

Campaign : Facebook
Bitcointalk Username: Biligma
Spreadsheet No: 425
Facebook Account: https://www.facebook.com/biligma.sugarova
Week#: 2

There are rules given. To be transparent and well organised, weekly reports are desirable options for the ICO managers.
You just send a report what you've done that week, but it really depends on the company's bounty programme you're in.

hi, read the rules until you understand, if one time read you still do not understand, try to read over and over again, or you can ask directly with the manager through PM, because not all managers want report with the same format

You live reply bounty is at the top right, trs just type, for example:
Week # 1 (16-22)

just se simple it only. You have to try it it's interesting

Making weekly report for bounty program  be it social media campaign or bitcointalk signature campaign is strictly according to the rules and regulations on the bounty thread it is clearly spelt out what to do and how to do it,  some bounty ask for reporting on a special form weekly on spreadsheets or give format on how to report on the bounty thread

Typically, the official bounty line of the program is written rules that you need to do for each campaign and when at what time to provide reports.

In fact, everything is simple. You should read the bounty branch for a start. On the branch everything is spelled out where, what and how. Examples (branch of a bounty, form, automatically)

Expand knowledge reading rules in threads. actually very simple, for example this week we do the work we follow. and by the end of week or the specified end date we report the work we did during the week.
if we see it has not been counted, it depends on the manager, so do not be afraid to stop doing the task for the next.
if accepted we must do the way until the end of the program.

LOL that is called rules mate. Manager does not spoon feed to any one who is participating on this forum bounty campaign. I see similar forum like for altcoin usages and then they are bounty program with signature and social media advertisement.
Please look into the same rules which can give the answer for what is the responsibility you have on bounty campaign that is also a fact one.

You may ask him to review any campaign website mate. That can may allow to learn and understand better.

On the first pages of the Bounty campaigns, the bount administrator writes all the details and you can ask him if there is a question. Some bounty campaign managers can be very busy or irresponsible, entirely luck.
