Just a quick statistic on the visibility of churches on the internet in Edinburgh.
I did an incognito search on Google today (meaning that Google ignored my previous search history and location) for "church in Edinburgh".
The first page of results (ignoring review links for two Church of Scotland churches which are tourist attractions) were:
Church of Scotland congregations - 1
Independent churches of various kinds, mainly charismatic - 6
The second page results were:
Independent churches - 4
Episcopal churches - 2
Roman Catholic churches - 1
United Reformed Churches - 1
My thoughts on this are that it reflects the age range of the people attending these churches. The older generation don't really use the Internet to the same extent as the young. These are also the growing churches that are actively seeking new members so they have a need to advertise.
