There is absolutely no reason why your on-page optimization should not be perfect. It can mean the different between your website showing up on page three of the search results and your website being the top listing. We encounter so many local businesses that simply ignore their on-page optimization (or the prior SEO company didn’t optimize correctly).
Monster-Traffic is another traffic exchange, though it’s initially a little off-putting due to the 1995-style website. It’s a free for all styled advertising list, where anyone signing up becomes part of the audience and an advertiser at the same time. You sign up and you can enter a link into their system, and that link is added to a roster that is send out to every member of the group. Additionally, registration allows a free solo ad; an ad that isn’t drowned out by other advertisers in that mailer.
