Too many people believe that having a presence on the WWW and registration with the major search engines should be enough to bring visitors to their site. The fact is that generating interest and activity at your site requires an ongoing, hands-on piloting approach. Yes, it is a vast world out there in cyberspace, and getting larger all the time. However, with a little energy and some good information, you can be noticed. Ultimately, it is content that brings people to visit you.
Information is the currency of the internet world, and offering it for free is a powerful tool.
The old adage, 'give and ye shall receive' holds truer here and is more apparent to see too. Always be thinking of new information that you possess that would benefit the community, new products you discover that will make life easier, new insights that will edify and enlighten. Whatever, just remember that if you breathe life into your site, it will reward you in return. Like any living creature, it responds and flourishes with food, water, and attention. So, do things like add monthly articles that you write about your field of expertise or interest, add links to worthy sites as a gift to your visitors, offer free advice or assistance upon request, and generally help, uplift, teach, and nurture your community.
