You don’t have to be better than your competition at absolutely everything, so long as you identify enough points to build a keyword strategy around. For smaller companies, this means that you probably have to be better at the things the bigger fish haven’t thought of or aren’t actively looking to do. If you can’t think of anything at all then you have a much bigger problem than just coming up with keywords…
I’ve always thought if you are serious about ranking – do so with ORIGINAL COPY. It’s clear – search engines reward good content it hasn’t found before. It indexes it blisteringly fast, for a start (within a second, if your website isn’t penalised!). So – make sure each of your pages has enough text content you have written specifically for that page – and you won’t need to jump through hoops to get it ranking.
The SEO starter guide describes much of what your SEO will do for you. Although you don't need to know this guide well yourself if you're hiring a professional to do the work for you, it is useful to be familiar with these techniques, so that you can be aware if an SEO wants to use a technique that is not recommended or, worse, strongly discouraged.
