If you have a web site, driving more sales is always a priority.
How you set up your site is very important to keeping people on your site and getting those sales.
The marketing tactics you use can be complex or simple, it's your site and your choice.
A lot of times the simple tactics can be the most effective ones to use.
Just having good headlines, value rich content and visual appeal can drive sales quite well.
One way is to make your site easy to navigate and view the information on the pages.
Try keeping sentences short with enough space between your words, sentences and paragraphs and enough white space to keep the pages appealing.
Also use strategically placed keywords and keyword phrases to attract search engines.
Use words that show the reader how your product adds value and grabs their attention and shows them "whats in it for them".
Here are some options you can use:

• Use bold text to highlight keywords or phrases
• Use bulleted lists to show value-added
• Use eye catching headings and sub headings
• Use graphics or pictures that are relevant to the content
• Highlight unique information or benefits

Other than these simple tactics, you also need to monitor your site to improve your strategies.
Check your stats to see how long people stay on your site and what pages get the most traffic and click-throughs.
Try different things to see what works and what does not.
Look at what other successful sites do and use some of those tried and proven tactics on your site.
A more advanced tactic is to use powerful copy to attract readers or using questions to lead your readers to convert which means more sales for you.
Try to position your site as an authority site to build credibility and integrity.
Never miss an opportunity to learn new marketing techniques or improve your site and make it a winning endeavor.
Don't over-think it or let it become a laborious chore, remember to have fun and enjoy the process!
