Facebook or blog?

In the rush to launch, I quickly added a 'blog' link on my menu bar that pretty much just redirects to my Facebook page.

I sent friend requests to my photographers/contributors and occasionally posted content around how our stock images were being used, links to interesting articles etc. Nothing too targeted and any content certainly wasn't going to win any Pulitzers.

I found:
- only a handful of photographers reached out to me or have 'friended' me
- hardly any end users/customers liked/sent friend requests or commented
- Google Analytics does not track clicks of the 'blog' link so I don't know how many people even view the Facebook page from the website
- it useful to recruit my second contributor, Katrina Brown. I walked her through our website and commission terms over FB messenger.

My gut feel on my lack of focus on this aspect of the website is that it's not being utilised most effectively. So I sat down to defined my desired outcomes for this 'blog'/facebook page:

- build awareness of Stockphoto.com for (and if possible, recruit) potential new customers and/or photographers/contributors
- if I can build a reasonable community, use it to maintain/keep track this network

I am keen to hear from other Warriors on their experience:
- in using FB as their blog. Should I opt for something like Wordpress?
- using FB to build a community of users and contributors (is it wrong to target both sides? Should I just focus on one user group?)
- what sort of content works? Should I be more sales-focused?
- do users even read the blog via the website? Is it a general waste of time?

Many thanks guys,
Jon
