You don't win your visitors' trust right away. It may take from 4-7 visits before they buy. You must always give them a reason to buy, and not offend them in any way because they will ricochet to other sites. Here's some things I do to get people to keep coming back to my site:
1. Upload new, original, and useful content often.
On every Web page put a notice: Bookmark our site. We update material weekly. Then, follow up and upload those free articles, book excerpts and tips. Blatant ads such as banners turn visitors off. Give them original information they can't find anywhere else.
2. Give information away for free.
People want and expect free information on your Web site. After realizing your value as an expert, they will start to trust you, and eventually buy from you.
3. Publish your own ezine.
Target it to your specific audience. If you help people find best career for them, collect emails from people looking to change careers.
Start with a monthly ezine, then see if you can do it bi-weekly. If you don't stay in regular touch with your possible buyers they will forget you and your products. People want to connect Online so they can trust you as their savvy friend. If they like your eMag they will recommend it to others.
4. Give people a reason to go to your site.
In your ezine, before you include your featured article, column, or other tips, place near top of it: Three Reasons to Visit My Site: Then give them an offer they can't refuse such as a free eReport or eBook. Next, follow that with other specials or discount offers you want to sell this particular month such as "Create Passive and Active Income with eBooks."
