Don't Mix and Match Those Domains

Many organisations like to do land grab with domain names by purchasing the same name with different generic top-level domains (e.g. .com, .net, .info), country code top-level domains (e.g. .uk, .es, .fr), and multiple second-level domains (e.g. .co.uk, .org.uk). Then of course there are mis-spellings, similar sounding words, brand names and trademarks.

Well all that leads to complexity, and it's not uncommon for many domains to be aliased to the same site in a way that any of them can be used to access the complete web site.

But it can get especially messy when SSL is enabled on some or all of the site too. Inevitably there end up being certificate warnings. Some organisations should know better. So when I was searching for providers of online and business privacy "seals",

I was very surprised to click on the link to an SSL page which was reported as using an invalid certificate.

Actually the certificate was fine, it just wasn't valid for the .ORG domain. Perhaps they had hoped the wildcard SSL certificate *.trust.com would somehow cater for *.truste.* - no.

Identity theft? Privacy? But apart from these configuration issues, isn't it just very confusing to have many different domains appearing in search engine results? How does this duplicate content affect their search engine ranking? Does it undermine trust in the brand? Should the SSL part of the site be indexed at all? Perhaps. Who makes these decisions? Is it the developers, the person who configured the site or does the business have a viewpoint?

I overheard a (loud) mobile telephone conversation this week in which a marketing manager* was apologising for a problem but they "did not know any of the technicalities". Mmmm, who is accountable? Make it your business to know.
