The folks over at Niche Media recently posted a great list of ways niche publishers can generate additional revenue online. Here's a few examples, but you can view the complete list here: http://www.nichedigitalconference.com/content/25-online-revenue-ideas-niche-publishers

1. Place each email you collect on multiple e-mail lists.  This allows you to send topically based messages. If a user unsubscribes you will not lose them completely.  Instead you’ll just lose them from one list.  Be sure to tell/ask users about this practice.

2. Engage your audience and create community by forming self-serve classified portals on the web.  You can start free and offer paid up-sells.

3. Encourage advertisers to use custom URLs to track success. If you look closely at Google Analytics, you will see a traffic statistic called "direct traffic". This can account for as much as 20% of total traffic and most advertisers do not track their direct traffic. Make sure you get credit for traffic that you drive to an advertiser's website.

4. Offer to do video interviews/demos for sponsors & advertisers as part of a digital bundle. As an up sell, make it available on your site, on their site, and on DVD (for offline mailing). Also, ask advertisers if they have promo videos for their product or service.  Then, create a channel to house and offer these videos to your audience.  Most advertisers have spent a ton of money on these videos and want to use them.

5. Create an e-newsletter from your sales team to your current advertisers with content that that positions you as a leader in the marketplace. Fill it with industry news, local news, upcoming issues, current hot topics, and your social media offerings. (Not just ad deadlines!)
