It is very common for a website to have more than one name. Deciding what to do can be tricky, and there may be no “correct” answer
Let’s say a station has 2 names a.com and b.com. When you go to a.com, it forces your browser to show b.com. This is the simplest case. The owner is trying to phase out the old name and we should help them.
You have the ability as a volunteer to do that. Click on the orange E and open up the Station Editor – copy / Paste the new name at the top, click update, then reload the station editor page to confirm that your update “took”
Now let’s get harder – you find two different names but neither web sites forces you to the other. Let’s say you find Froggyfm103.com and 103bullcountry.com. Which one is right? One of them probably isn’t even for this radio station, or may be from a prior owner. Now is a good time to click on Wiki – there may be a very obvious explanation. Look at the bottom of the page for the copyright date, call sign, owner – look for a Contact link that will likely (but not always) give you a call sign and city where the station is located.
This is where doing your local stations first helps, because you know the geography. Is Scotts Bluff Nebraska close to Omaha? I haven’t got a clue without pulling up a map. Someone who lives there or maybe a retired long haul truck driver would immediately know. [don’t post a comment about where Scott’s bluff is]. You’ll eventually figure it out.
Do NOT rely solely on Wikipedia, though. Look for news stories in Google using the preconfigured Google links. I really don’t expect volunteers to do deep research – you always have the option to click ignore station and move on.
Now the hardest one is a station that has two names, and they are both correct. Brian fed me a great example – WCPN-FM in Cleveland, a city he knows well
Note that the station is owned by “IDEAStream” – the editor says the station web site is http://www.wcpn.org/, which matches the call sign. Clicking through, you’ll find a web site for IDEAStream that lists WCPN, their PBS TV station and a classical music FM station. They are three different stations. That web site is called http://www.ideastream.org
So which one is right? Probably the important part is that neither one is wrong. You confirmed that WCPN.org got you to the correct web site. The URL is accurate. Significantly, clicking on it to not change the name in the address bar to IDEAStream, so they probably intend WCPN.org to keep working. If I were doing this, I would leave it as it is.
The problem that would find if you change it is the editor will start nagging you with “is this a simulcast?” when it sees stations sharing the same web page. These stations are not a simulcast, just grouped on a single web site by the owner.
For now, the priority is to clear the warning that the URL is potentially unsafe. Clicking “Accurate” solves that. Once the triage is done, we can do more fine tuning.
