Setup joint ventures with site owners in non-competing, but related, niches. For instance, if you sell surfing info products, you may want to look for joint venture partners who sell surf boards and wet suits. Clearly communicate the benefits of working with you whenever you contact a joint venture partner in an attempt to grow your opt-in list.

Compile a list of forums related to your niche. Open up accounts on all of those forums and begin posting regularly. Once you have established a reputation as an authority or at least a knowledgeable person in your niche, create an attractive signature with compelling copy that links to your free opt-in page.

Create 'viral' audios to promote your list. Start by creating a rough outline for your audio, so you have something to follow during your presentation. Discuss some specific aspect of your business and then close with a call to action. Tell the listener to go to your website and join your list to receive some type of benefit, which will allow them to use what they learned more effectively.

Consider setting up a joint venture list with other successful business owners in your niche. You can each agree to write one or two lessons in the series. In the end, you will have a series of powerful lessons that position you as an expert by associating you with other experts and that also have a natural upsell mechanism built in: affiliate programs.

Test a short copy format for your landing page. Depending on the information offered, you may be better avoiding a long, grandiose sales page. Instead, stick to some important bullet points and make an attempt to fit at least 15% of the opt-in form above the fold, so visitors can at least guess that it is coming up.

Find ways to integrate opt-in forms into your general website layout on each page. Consider putting an opt- in form on the sidebar menu of each page. Additionally, consider putting an opt-in form on bottom of each page. Give each visitor the chance to sign up for your list, regardless of where he or she arrives.

Compile a list of blogs related to your niche. Determine which of these blogs have the highest Google PR rank and lowest Alexa ratings. Make an effort post useful comments on them at least semi- regularly. Include a signature with a link to your opt-in page. If the blog receives a considerable amount of traffic, you should also receive some traffic from direct click-throughs.

When building a list, always give before you attempt to receive. While this applies to Internet marketing in general, it is especially true in list building. If you do not freely give powerful advice, software, and information to your list members when you first begin building your list, you really cannot expect them in turn to be willing to shell out money when you launch a product.

Of course, it's impossible to put everything about list building into just one article. But you can't deny that you've just added to your understanding about list building, and that's time well spent.
