Do you mean your site is indexed? Yes, content is a great idea if you want traffic LOL.

I think content is so important for your marketing because it gives you an opportunity to stay in touch with your customers without always asking them to buy something.You gain an authority in your chosen niche. I advise you to read posts by Dylanrieger. I have learned a great deal of marketing from him. I wish you good luck on your blogging journey!
