Not every book is worth money. In fact, the sad truth is that most books aren't worth the paper they are written on. In general, non-fiction does much better in the used book world than fiction. There is, however, a quick way to decide which books to sell on Amazon.
Amazon: Amazon is the internet's top shopping center. If you can think of it, Amazon probably sells it. But how can it help your small business? It gives your products an exposure to a large audience – something that any small business owner can't complain about. But beware of fees. Everything you list and sell on Amazon, similar to eBay, you will have to pay seller fees.
While you are writing your book (and if you are absolutely serious about self-publishing it) you should be deciding on a title, buying a block of ISBNs in your company's name, and listing your book in Books in Print.
Think of animals. In nature, each animal has its natural environment, or habitat. Some nest on the ground, under the ground or in trees. Placing bait in the right spot can attract the animals you want to see. The same principle applies to niche marketing online. You will need to strategically place your goodies in order to attract those hungry for it.
If you have a website, you need to be able to build links in order to increase your traffic and get link juice from other sites. Link juice is a term that is used in the SEO industry to describe the benefits that are received from getting a link from a site that has a higher PageRank than the one it is linking to. When a site provides a one-way, do follow a link, it passes link juice to the site which it links to. link building is a task that requires a lot of tedious effort. And, if you are not really sure of the correct way to build links to your site, you might not be doing yourself any favors. A quantity of links is not what is important. The most important thing should be the quality of the links which are built.
Focus your SEO efforts on creating great content, and then promote that content one link at a time. Use some creativity to come up with a guide, resource, online tool, etc., that your niche might find really useful. Then, once that piece of content is created, focus on promoting that content using SageMailer, other site owners, etc., and asking them to review your content. If the quality is high and the content is useful, it WILL get you links.
While these frequent updates are not good for websites and a little awkward for internet marketers, they are brought to dislodge spammers and schemers. Provide genuine and meaningful information and get natural links. The important thing to learn to build a loyal community and make them actively participate.
