(And yes, I'm fully aware that I'm using an outdated Google service created 15 years ago with terrible formatting. And an AOL address. Cue the snorts. I've addressed this before and I'm kind of stuck with it. And yes, it's because I've "always done it that way." Mind your own damn business.)
The Grand Lodge of Ohio has circulated an online guide to lodge internet management and content creation at www.freemasonmarketing.com . Created in part by WB Matt Johnson, it has a lot of resources in a single place. If you find that you are suddenly the newly appointed Internet Committee, you need to look at this information or get help.
Even if you DO create the world's greatest website, it's worthless six months from now if it doesn't have up to date information about how to find your lodge, what's going on regularly, and who to contact. Everybody seems to have migrated to Facebook, but that's not really true now. There's a certain subset that has shunned it in favor of the Next Big Thing to view on their phones, once their grandparents all got Facebook accounts. More important, Facebook pages are lousy for finding important information like addresses, contact information, regular meeting nights, lodge histories, archival photos, and other unique aspects of your lodge that might make it stand out. Try searching though old Facebook posts to find that sort of information if it's been posted more than six months ago. Facebook pages are chaos, and depressingly few Facebook sites have a fully filled-out "About" page.
Good old fashioned websites exist as the closest thing to a semi-permanent online billboard for your lodge (or as permanent as anything can be these days), and it's where everybody winds up eventually, no matter how they got there, and they will for the foreseeable future. I can talk into my iPhone and in 3 seconds get the website for any lodge that has one. And it's remarkable how useful even old, defunct lodge web pages are that can still be found using the Internet Archive Wayback Machine.
If you just can't manage to get someone who will update the site on a regular basis, or last year's Senior Deacon ran off to Wyoming with all of the site admin access information and passwords, then create a website that at least has the basics of where you are, WHAT you are, and who to contact that doesn't require regular upkeep. At least it's a place to start and you won't be invisible. Think of a simplified website as the electronic sign on your lodge front door.
If your lodge DOESN'T have a website at all, I promise you are doomed to extinction. Yeah, it's that important.
