Waiting time for results after a Backlink campaign

[fafa]

Hello everyone!
I bought a new domain name 12 months ago with the aim of making it a niche site and thus remunerate it with an affiliate program. I spent almost 10 months writing a hundred clustered pages. At the end of these 10 less work, I did not obtain much like results for lack of backlinks <<I did not make any backlinks in 10 less>>.

In the period of the 11th and 12th less, I led a netlinking campaign by writing more than 30 sponsored articles in the sites of my theme, 10 themed forum links and 1 article positioned at a competitor.
So far, I do not observe any change, on the contrary a decline in position. I remember that I made 10 clicks and 300 impressions per day according to the SEARCH CONSOLE. Now that is no longer the case.

I need an explanation on the waiting time between actions and results in netlinking or even useful advice for me.
THANKS...
