I really do not use these tools — and in my point of view, it’s just a waste of time.
some bloggers use these kinds of tools — but as far as I know, expert bloggers usually do not recommend.
if some of them recommend but these tools are not essential in the blogging journey.
it can be a choice to use or not.
but personally I do not use it.
Another thing here I will mention as an example –

Seth Goddin — This man is an expert marketer he has a blog and a few 1 or 2 years ago he was using domain — typepad . com –
I mean a sub-domain site.
neither this man use outreach tools or other complex plugins.
I doubt that Seth goddin does not use analytics.
Whatever — — long story short — — He is simply Blogging — and write 200 or 300 words blog post daily without adding a photo.
But people including me wait for his post daily.
Thanks
