could it be said that generally for the smaller business a spend of £1000 should return £10,000
How are you looking at this?
Are you differentiating between
new, untested marketing and
continuing marketing?
What do I mean?
Imagine 2 identical businesses: business A and business B.
They both run ads in their local paper.
Business A's ad is well thought out and well written.
Business B's ad is just a "we do x, give us your business" type ad.
In the following days, business A gets a few enquiries and those enquiries bring in a profit that more than covers the cost of the ad.
Business B: the phone doesn't ring, except for one guy who's shopping for price and decides to go with another company.
Now, company A is likely to run the ad again next week. Company B is likely to dump the ad.
Now, imagine that company A runs the ad every week for a year.
The average return for the 2 companies is:
[(52 x company A profit) + company B return (a negative number that is the cost of the ad)] / 53
i.e. it's heavily skewed towards the successful ad.
However, the return from the
new, untested advertising is
company A profit + company B return
which could be either positive or negative, depending on the size of A's profit.
Hope this helps.
