Do you need retargeting for your site?

Question

Search Engine Optimization

Good afternoon! The company is engaged in security systems (cameras, barriers and metal detectors, etc.)
We conduct contextual advertising and move the site to SEO.
The question arose, does it make sense to collect a retargeting base with 120 visitors per day in this area?
If yes, please explain to me, because I don’t catch up at all: in contextual advertising there is display advertising that is spinning for a large number of people. What is the point of retargeting?

Answer 1

marketing is a tricky business

-- Hello, we are very glad to see you in our store holding cultural customer service month!
- Give me a couple of rolls of toilet paper.
Unfortunately, we don't have toilet paper for sale. But on the other hand, we can offer you in return, a choice of Velcro, confetti and emery, the third number!

marketers say that there is a sense,
I don’t particularly believe them, because it’s like knowing what click brought the buyer,
but if budgets allow, test
there is AB and all that,
but soap, of course, is more reliable

Answer 2

A person thinks to buy something from you, came to the site, then went to competitors, then just forgot, and you kind of hint to him that you had it. It is clear that conversions can be achieved for such an audience much larger
