If you're someone who wants more traffic to your website (I'm guessing you do?), having a beautiful website designed is just the beginning. (A vitally important beginning, but a beginning nonetheless!) Building a website and waiting for traffic is like building a brick-and-mortar store in the middle of nowhere and waiting for customers to just show up. If you build it, they won't just come. They need to have a way to find you first.
In steps SEO. Search Engine Optimization. Maybe you've heard of SEO but it just sounded to nerdy or just sounded over your head. Let's break it down into simple terms: SEO means using keywords that your ideal customers would type into a search engine to find what you're offering.
So it's up to you to figure out what those keywords and keyword phrases are that your customers are already out there searching for and crafting your website's content around those.
It used to be that your website's homepage was the first page that everyone saw. It was like walking in the front door of your business. But nowadays, the vast majority of traffic comes from search engines. And search engines want to send visitors to the most relevant place based on the keywords they just typed in. This place will most likely be a page on your website that focuses on that specific keyword phrase.
By the way, this is why blogs and forums are the most powerful way to increase your website's footprint with quality content. Each blog and forum post has its own page that focuses on one specific subject (a keyword phrase). Blogs are where content is generated by you (the website owner) and forums is where content is generated by your users.
