Aye, good point above! If you are going for a ICT / Web / Social media job then yeah I would put your online earning down otherwise it may do more harm than good.
In an about turn from me, I should take
@rninja 's request and be a little helpful.
blogging - if you are going for a job in social media mention you have a blog with 'x' stats and 'x' engagement. Otherwise no.
online surveys - Don't mention this. It will make no positive impact on your CV
mystery shopping - Outline the companies you work for as any job. Advise what you do in that role. Its an auditing role. Mention your acceptance rate (100% unless you've failed some audits but not mention them!), the different types of audits/companies (mention brands you audited).
comping - Never mention this
reselling - Some people will say this is relevant to a sales-based role. I'm just not convinced. ,
task apps - a hard one but I'd say if they are MS tasks they are relevant. If they are auditing then they are relevant. Anything else isn't.
There is a different working world out there and lots of things can be great but most businesses just don't understand it. I tend to keep my 'out-of-work' stuff very seperate from my 'in-work' stuff.
That works for me.
YMMV
