Well... I wouldn't call them articles really. Just long descriptions that are unique. My assistant has been writing little bits of content on my site for about 3 months now and I have approx. 200 pages of light 200-250 word unique content with pics. Would it be worth my while to go back and kw optimize these small pages (change url/title/meta/include kw at least once in content)? Not really sure how much weight these little pages would carry and if it would even be worth my time. Was using her posted content as just small daily filler while I was posting larger articles.
