I will ask for money after guest post
dont worry about this
If I am a client I would like to know first what is the niche of the site where you are posting about my project, so I can check and see if the niche is the same as mine, so I can also check if the stat that you're showing is the same like the one that you just showed, transparency is important if you're going to offer this kind of service, if you have a site with this kind of stat you should be proud of it.
