I like this article,
How to do SEO the Lazy Way, for two reasons, one is the author is instructing his readers how to best utilize their
virtual assistant to complete routine
SEO tasks - and the other is because the list of steps to follow are (for the most part) applicable and doable even for people who have no experience with
SEO.
I will say that I don't necessarily (personally) recommend or utilize the for-a-fee options he lists here - good
SEO can be done without this, but it's clearly working for him so if you do have a budget for these kinds of things, it might be worth looking into as well.
That said, look at the items he lists that don't cost you anything but time and see what you can do to help your own site rank better in the SERPs.
