12) Write your own content. Use only content (pictures, text, videos, ...) made by yourself or with explicit permission, everything else probably infringes someone's copyright.

13) Check and double-check your content. Use a spell-checker, and have someone check your texts for correct grammar. Some people are really turned off by those kinds of errors and it can cost you a potential sale or ongoing client. When in doubt hire a copywriter or even someone to proofread your own writing. You usually only have one chance to make that first impression and if you take your content seriously then a small investment in the services of a professional writer will be well worth your money.

14) Try to avoid placing banners at the top of your page. If you run a site that depends on advertising you might want to ignore this suggestion but for most sites, banners will instantly take your customers to another site other than your own and you will lose the sale. If you have to have banners or advertising on your site, limit the number of banners on your site to no more than two per page. One is ideal and try to make the advertising relevant to the content to add value.

15) Promote your content. The most important thing to remember is that content without promotion is well... just content. You need to get the word out that you have something important to say, get your site address in all of your advertising, get your site listed in search engines, write industry specific content that can be provided to other sites, and in general do everything you can to get people to your site where you do your selling. You can do a lot on your own but consider hiring a full time professional if your site is important to you. The money you spend will be returned ten fold (and I can guarantee it) if you follow the rules provided in this article.
