Not having an online presence at all is a certain way to make your club invisible. Having some form of online presence, but no website, means that you get some exposure on line, but it's hard for people to get in touch with you.
Other forms of online presence might get your club found by enthusiastic Rotarians, but you remain hidden to potential new members or other supporters.
Of course, in every scenario cited below, the success or failure of whatever strategy you adopt depends almost entirely on your club's commitment to keep its information up to date.
Your club is impossible to find other than by a dedicated Rotarian who is determined to track you down. Potential members, potential visitors and potential supporters will never get to hear about you.
Even if you run advertisements in your local paper, put flyers in your local traders' windows or do letter box drops, the first thing people do these days is look for you on the Internet. Right where you don't exist.
Facebook users, too, look for a website to go to when they want more information.
Having only a FaceBook page is like printing brochures and handing them out - but omitting your address, phone number and other contact details. Readers say "Wow! I really like this!" but have no way of contacting you. Even if they go on to Google and search for you, all they'll find is the original Facebook page they started with.
A facebook page is great publicity, but it doesn't actually do anything. That's the role of your website. Without backlinks, the most effective and simplest way for somebody to get to your website is missing.
Google takes into account the number of links from external sources back to your website; social media with links to your site will significantly boost how important Google considers your website.
At most this will tell people that your club exists, and might even give a location of your meetings. There is no way for interested parties to get in touch with your club other than perhaps by a member's email address.
This type of listing is notorious for being out of date, and usually relies on a third party to make changes.
This type of listing is usually under some sort of "club finder" link or menu option. It's useful for visiting Rotarians to find out where and when you meet, but it's of no value in publicising what your club does. Such listings will not help in reaching potential members, unless they've already decided beforehand that they want to join a Rotary club in your specific location.
A web address of something like https://clubmanager.ca/rotarybullamakanka succeeds admirably in promoting clubmanager.ca, but does very little to promote your own club. Similarly with a web address like rotarybullamakanka.nswclubs.com really helps nswclubs.com, but not your own club.
The ideal strategy is that your club has both a Facebook presence to maximise exposure and publicity, with a website and proper domain name, through which people can make one-click contact with you, book events, subscribe to your newsletters and so on. Your Facebook page must refer visitors to your website as part of your online strategy.
Directory listings are useful for fellow Rotarians who might want to visit you, but of very limited value in reaching non-members.
