SEO (search engine optimization) is the process of increasing the quantity and quality of organic traffic to your business website.
The first goal of SEO is to draw the highest quality traffic to you site. What does this mean? If you have a local liquor store but Google is telling internet users that you are a bar and grill, the current SEO efforts are working and need to be refocused so that Google is crystal clear that you are indeed a liquor store. You need to then make sure that all content and SEO related assets, on both the front end (the visible part of your website) and back end (under the hood, the part of the website that you don't see) make this clear to Google.
The next goal is to attract more of the high quality traffic that you based your initial SEO efforts on. The more high quality content that you create for your website, the more that Google's crawlers have to gather and the more your site is vetted with Google.
Creating awesome content (blog posts, infographics, videos, etc.) makes people want to visit your site as well as share the content with the world. Google likes this because it wants your pages to be interesting to users and come off as authoritative. This will ultimately win for you because this will only make Google want to show your website content to more people. Don't forget to use phrases and words that are going to appeal to and resonate with the people you ultimately want to convert into customers and clients.
Many other elements such as meta descriptions and title tags must be in place and executed perfectly to bode well with Google's crawlers. You don't really need to understand these elements in depth unless of course you want to learn how to do SEO yourself. But if you are going to hire someone to do your SEO, you will know that they know there stuff as over time you will start ranking higher and higher as users are searching for the solutions that you can provide.
Don't forget to make all of your website content easy to share. Beyond that, make sure to keep it coming! You really can't do enough content creation as long as it's genuine, authoritative and provides value for the user.
