Satisfaction Guaranteed
Would anyone ever buy from a store where it's not? A satisfaction guarantee is implied nowadays and listing that you offer one is a waste of characters.

In Stock
In Stock Now can work if you're selling a hard to get or seasonal item and you want to drive home that you actually have it, other than that, avoid it. Otherwise it's implued. Why would you ever list an ad to sell something you don't have in stock?

Company Name
Is your company name one people will recognize? If not, son't waste characters listing it. Instead focus on offer or product. If you manufacture a product that is sold by resellers and you also have an ecommerce site, 'Official JoeWidget Site' can work to distinguish you from others in space.

7. Create RSS feeds for your site and submit feed URLs to major RSS feed directories online. A good place to start is http://www.guidetorss.com/ which provides a list of top RSS directories.

8. Be an active commenter. Try to leave comments on blogs that you regularly visit. Most comment systems also provide a way for you to leave a link back to your blog or website which begs a visit at very least.

9. If you plan to have anything printed up, put your web address on it. You can print your URL on business cards, stickers, leaflets, etc.

10. Add your web address to your forum profile signature. Every time you post or respond to questions your ad will be displayed. If you post good content in forums, people who read your threads will also check out your website.
