I have a client who is a marketing & PR firm with industry specialties in tech, healthcare and government. They have a WordPress blog hosted by WP but it appears under their domain as www.domain.com/blog. The blog is appended frequently with unique and useful content that is interesting to visitors.
The blog content never speaks to the marketing & PR industry or issues. The content speaks exclusively to the tech, healthcare and government verticals, the industries that this PR firm serves. In the blog postings there is never a call to action, no closing phrase like "we know your industry well as we have demonstrated in this blog so give us a call ! "
Considering that the frequent posting will attract spiders and the content will interest potential clients in their respective industries....
Does this hurt or help overall SEO? Is this a non-issue - the issue of the blog content not talking about PR issues within its industry specialties?
