The trouble with 1-2-3-4-5.com and 5-4-3-2-1.com is that they are difficult to say.

Google treats them as an equation

Their ratings algoritms say that the domains have no value because they are just numeric with lots of dashes - which breaks the rules for acceptable names - so I think they are automatically penalised.

What the AI default behaviour doesn't appreciate is the humanity of - these are important sequences - easy to type - beautifully symetrical - stand out in the crowd, and on displays

I still believe in them!!

But perhaps SiteAtlas.co.uk is a better name?

There are billions of SiteMaps, but only 1 SiteAtlas
