How to use Facebook to increase web site traffic without boosting posts?

Without boosting posts? You mean without posting too many status updates, links, notes etc?

Website traffic increases substantially with your website gaining a higher PageRank, since your search engine result positions (SERP) will become higher, the higher your PageRank is. Gaining a higher PageRank, on its turn, can be achieved by posting the very FIRST link to your website on Facebook, being a high PageRank website (now9, used to be10) with probably the most dynamic content on internet.

Off course other simple techniques may help, like creating an account or a company page, fan page with name corresponding to the exact name of your company, so it can be looked up without a clickable link.

Facebook is not same for free publicity business, you have to Boost post or pay to third party for web traffic promotion.  if you have old page with lots of active fans that can help . Facebook now forcing business to pay for reach to their own page fans. 

"Your content has to be interesting"

Facebook has been recently switching from organic reach into paid reach. The process which mainly SMBs hope for in achieving a better reach without paying doesn't match Facebook's plan. The company is moving towards quality content and not an open market ad space. So unless your post has something interesting or might have some engagement with your friends/ fans, don't expect any high conversion rates on your website/ link . 

Hi Linda,

Below are some of the tips which I follow to increase traffic and branding for my clients. I hope this would be useful for you.

• You can display as many as5 ‘Featured Likes.’ These are Pages that are liked by your Page on your Facebook Page. Another excellent technique to use is to ask your Featured Likes to return the favor for you. This gives you a little advertising drop. 
• Add your Facebook URL to all of your marketing opportunities such as letterhead, business cards, brochures, etc. Make sure that you use a customized Facebook URL for your page, because the assigned URLs are long and ugly. 
• If you want your fans to visit your page often and share it, then you need to make sure you offer content that’s of value. If you consistently provide top-notch content, your fan base will grow as your reach grows. In addition, the first time someone finds your page they’ll like what they see and want to read more of what you have to offer and so they are much more likely to ‘Like’ your page. 
• If you haven’t already taken the step to create a newsletter to send out to your customers and fans, then now is the perfect time to do just that. MailChimp along with other providers provide a simple newsletter solution. You can also post on your Facebook Page when your newsletter is available. Do a good job and provide valuable content so that your fans share it and you grow your fan base. 
• Planning is important and being able to plan in advance what you want to post about helps you to schedule and organize your themes. This creates an environment where you can tie themes together with what’s going on in the community, online, etc. and then you can create valuable material that gains even more power because of your ‘timing.’

Remember for your Facebook Page to be a success you need to grow your fans, so nurture it 

and care for it!.

You can also try: Contests and Like Gated Coupons.

• One of the easiest methods to interest people and draw them to your page is using contests. People like free items and so you can see why offering something free would increase new fans to your page especially when the condition to entering the contest is that you must like the page first. The lure of winning a prize helps you to target your market and grow your likes. 
• Coupons are another great way to promote your Facebook page. The coupon doesn’t have to be big. It can be as small as10% off a purchase. It is a great way to provide your audience an incentive to purchase the product(s) you offer and you can still keep your profit margins looking pretty healthy. 

Thanks and Regards
