There are two forms of digital competitors:
Same industry different place
The internet does not respect geography. Although there are businesses similar to yours off-line you never compete because they are too far away for clients to consider using them. On the internet they are all as close as your client’s computer screen!
Different industry same keywords
On the internet you compete for search terms or ‘keywords’
Often you will stumble across accidents of language where the popular description for your offerings coincidentally and unfortunately matches a description in a completely unrelated business or industry.
e.g. You hire indoor plants so your keywords might be plant hire but that’s also what the civil construction industry use to describe earth moving equipment hire !
