SEO stands for Search Engine Optimization. What it refers to is, simply put, optimizing the pages of your website so that it has a better chance of ranking well with the search engines, and receive better results in relevant searches. Most website owners would like to have their websites appear on the first page of a Google search. This is great for business! Having the pages of your website optimized really helps your chances of this happening.
Some of the aspects of SEO include Keyword-Rich title tags, meta tags and copy (the text of your site). These are things that your website developer can implement when coding the pages of your site. This is “On Page” SEO.
One of the most important thing you can do to really improve your site’s importance to Google is to have as many one-way, inbound links from other sites pointing to you. This indicates to Google (and other search engines) that your site is an authority in it’s field. It helps if these sites that link to you are in the same field as your site. For example, if you sell bricks, it helps if these other sites are related to “bricks.”
There’s a lot more to this subject than this post, but hopefully this gives you a little bit of an understanding on what SEO is and it’s importance to a successful website.
