Google map embeds, Google custom maps, google map stacking etc. I finding these services to help with local SEO. I"m hoping for some impartial information around these. Are they useful? Are they dangerous (likely to be penalised by google? Thanks
That said... sure, they can help. It`s one (of many) ways you can signal your location - which can be important for many businesses. It`s one (of many) ways to signal where all your branches are (if that`s applicable).
It used to be that "Location, Location, Location" was only really important for real world businesses. Now, it`s important online, too.
However if you are using them alongside content - they are very useful and do get a lot of traffic which leads back to source.
I use them on hotel sites that create things to do, best restaurants, etc
You can test it for yourself how rubbish this is - create a map - put your label on a landmark somewhere / anywhere - wait for it to be indexed and then search - landmark name and your service - voila nada, zip, nothing
