Organic Search Engine Rankings refers to where your page appears when someone types in keywords in a search engine such as Google. Your site needs to be optimized to get the best possible ranking.

Your typical Shopify theme is already compatible with the technical aspects of SEO (Search Engine Optimization), following the design guidelines that make it easy for search engines to index your content, but first they have to know about your site.

Submitting your Site

To get started, you need to submit your site to the search engine. Here are the links:

Once you have submitted your site it is added to the queue so that their "spiders" will index it - normally after a few days.

Tuning your Keywords

While you are waiting, you might want to spend a few minutes tuning your page content to your specific keywords (you have specific keywords right?). You can get an idea of what the search engines are seeing by using this free tool: http://www.seomoz.org/term-extractor. It will analyze the content of your page and extracts the terms that the search engines are seeing. Hint: it doesn't hurt to run this tool over your competitors' sites as well, to see what they are using.

High quality content, tuned to your keywords, is the single most important factor for improving your organic search results.

Using Paid Search

You can also use paid search (i.e adwords aka PPC) to help your organic rankings by raising your quality score. For example, you can run a low budget adwords campaign that uses your keywords. Your initial quality score will be around 4-5 if you have decent content. If you follow the adwords help on improving the quality score to at least a 7 you will find your organic ranking will improve as well.

Linking

Another critical factor in your organic rankings is how many sites are linking to you. Search engines consider links as votes, but not all links are equal. An "authoritative" site, i.e. one that has a lot of links itself, will have a higher value.

Domain Age

The last thing I will mention is that Search Engines factor in the age of domains, which means you have to be around for a while, and patient. While we are on the topic, you should know that the GoogleBot loves to see fresh content as well, which is why blogs are so effective.

Bottom Line

My advice is to first and foremost create compelling and valuable articles on your blog, and have remarkable products. Then, make it easy for users to link to your site by using services such as addthis and Facebook Like on your pages.
