Off page seo doubt

I have created two Amazon Affiliate website few days before, both having 1 pillar conte, 5 blog content and 5 review content.

I submitted the sitemap and few url got indexed.

So shall i start off page seo now?

Can i do pbn, web2. 0, guest post, blog commenting, social book marking?

How many pbn, guest post, web 2. 0, blog commenting, social bookmarking should i create per day?

Because it is new site.

don't go off -page now for the new site because google will red flag. wait for 3 months and do contextual link building

Wait until most of your urls got indexed, after seeing some progress in ranking. If you don't see any progress from your on page seo make it strong then go for link building.

Continue adding content and let the site age a bit. 3 months, as outlined above me, is a decent waiting period. 2 months might suffice as well. In that time, perfect your onsite SEO, interlinking and densities. And churn more content, that always helps.
