Which is most effective for promoting my site and does google adwords help with page optimising

The simple answer is both.you want to have your site as optimized as much as possible, to get the best results in the search engines, as its free traffic.adwords can work very well, or very badly. its something that takes a lot of practise to get right, and not something that can be easily learnt (as the methods are different for each industry). start off with a small budget, and keep trying until you get results, and then you can increase your budget.the best results come when your website is on the first page of results in the search engines, and in google adwords, as this gives you maximum coverage.
