Often times I sit with my son and daughter and find educational websites, including videos on YouTube (usually of giraffes, zebras, elephants, etc). Today, my son asked to see talking couches. He's four. So, I looked for videos of talking couches and I was not surprised to find the first result below. My son, on the other hand, was extremely excited to see a real live talking couch!
This goes to show one thing. If you are looking for something specific you can probably find it on the web. And if you sell talking couches I hope that you are shown on the first page of search results. How do you do that? By following search engine optimization techniques and updating your content frequently. Using a web content management system that lets you do both is a great start.
