My question is would you concern yourself with this or not worry? Basically you have a template/layout for your landing page/s and in the footer of the landing page, linking to articles, using wordpress on the main domain to have a handful of articles in place, for the sake of the landing page not being a one page site etc. Would you be concerned that the template you use for the wp blog for the articles and the html landing pages are different? i know i could get the landing page layout coded for the wp blog where the articles are but id rather not, after all its the landing pages i would be sending traffic to (PPC) and im mostly linking to the articles from the landing page footer so that its a mini-site i guess, along with your usual privacy policy, terms, about, contact. I guess i could get a wp theme as close to (in color) as the landing page colors. Were talking AM/PPC here, with QS in mind, so the reason for not wanting to setup single page langing pages. Whats your opinion on this please?
Why couldn't you just match the colors of the landing page with the colors of the theme ? Just open the CSS files of the theme and match them up. Or what I also do is just make an ad (480x60, 300x250, or what ever) and place the ad on the blog. Not sure if I'm understanding you correctly, but I hope it helps a little.
