Your friends are exactly who you should ask about building a website or doing search engine optimization, because that is their expertise. So, when you finally decide to hire a website developer, an SEO person or a company that can handle all of your media needs, you can tell them exactly what your friends, the experts, have told you. After all, why trust the people who have been doing this for a living for a couple decades when you’ve got such great friends to tell you what do to?
Everyone is an expert, if you ask them. Just remember, free advice is worth what you paid to receive it.
One more thing: I’m sure your friends will be happy to pay to fix everything after you follow their advice and it fails.
