Profile Bio Links: this is my intention, what do you recommend?

After reading few tips, i m still confused.
Can you please explain, What type of URL should we put into our bio? fresh domains or authoritative domains?

Which works well? a popular url shortner or can i build my own url shortener redirecting to my new domains?

I have fresh domain, i haven't done any SEO tunning on it even though they are SEO optimized.

so what i m planning to do is
IG->bitly/my_url_shortnere->my_landing_page->links/buttons_to_my_cpa_offers

which works perfectly?

I have a 2 weeks aged account which i m trying to seed. can i start placing the links? or i should seed the accounts first? or for how long should i wait?

Is it safe to use free domains ?

If you want to be safe I would use this setup. One domain you bought (.com) - A web 2.0 landing page (like weebly) - Then on your Web 2.0 a call to action to bring traffic to your Affiliate link or your CPA offer.

I suggest to wait 1 week before placing a link in your bio. And never use free domain. These domains are use to spam an they are saturated and often instantly blocked by instagram. I hope it helps

You must remember that IG crawlers are badass and top of the line
