make sure you link to good ranking sites that are relevant to your industry. this will help a lot in ranking the site well as the links back to your site help google index it more. make sure your keywords and meta tags are relevant to your business. make sure you have good html links in your pages that link back to themselves. this also gives google bots more to crawl. they like to crawl so give them something

make sure your content heavy and that each page has relevant description to what your keywords and tags are. make sure your h1 tags, h2 tags are there on each page. all these elements will have google indexing your site correctly and will push you up the rankings.
always remember that google likes to have updated info to crawl so just by tweaking it every now and then can all help within the rankings.
i changed my website a while ago and most of my pages arn't even indexed properly but because of the content of my last site and links i have coming into my site it hasn't suffered. Once i've tweaked it with my new info i will get it indexed properly again
