Very nicely put mate.
What were your budgets for each of these though?
We had a budget of 6000 dollars per month to begin with when I proposed the idea of paid. We spent around 10'000 dollars a month for SEO, which we didn't use at all at the end, as we did content creation via email marketing and sms only later on.
At first, we used remarketing only with GDN as it's the cheapest return on ad spend.
Later on, we were at 15'000 per month with google ads for the search... as the paid strategy improved, we began to use the same amount for youtube ads.
You can definitely test things with 150-200 dollars a day to collect data and improve the search ads and improve the way your keywords appear and speak to your customers in the conversion funnel.
And most people don't realise it but it can also help to test titles for your SEO articles and see which ones give you the best CTR.
Despite google ads...
GDN is still for me the most powerful lead gen machine, many brands use it for awareness only, it's what you are taught in marketing schools but after testing a lot, I realise it's stupid and a waste of money to "perceive" it as an awareness channel. We should always think about GDN in terms of lead gen, NOT AWARENESS as it comes automatically with the lead gen strategy. I also use it for sales in the remarketing stage.
I have yet found another channel where businesses can have 20k leads in a single day so easily, nothing beats it... GDN can touch 95% of the worldwide population every week let's not forget that.
+ if you do print advertising in your city or country... you should use GDN to see which banner ad is having the best CTR before you start to print your banners everywhere and bleeding cash like most physical businesses do.
Google's advertising ecosystem is so useful for so many things.
