And since all three of these things are quite difficult to determine, I recommend approaching the problem in reverse.
For presentation websites, the return on investment is the number and value of contacts that the website "generates" (so-called leads). At least that's how you can think about it at first for simplicity.
number of conversions * conversion value = return on website investment
Of course, it's different for e-shops, but more on that next time.
I am a florist and my website gets 150 visitors per month. 5 of them order floral arrangements fo paraguay phone number data r their celebration. I have a net profit of 5,000 CZK for each arrangement. The calculation could then look like this:
5 * 7500 (5000 net profit + contact value) = 37,500 CZK / month.
The above also implies that if you are creating a website that does not have the potential to generate anything back for you (for example, a wedding website ), it is, in my opinion, a sensible idea to invest as little as possible in it.
What's the catch?
You might argue that this is a game of pure guessing and as such there is no point in dwelling too much on it.
I partially agree, but I still think it's worth it.
