Hello I have a home website which i want to have portals to 3 of my other websites. And i am wondering from a SEO perspective if it would be better to buy 3 new domains instead of makeing subdomains(for a forum for example?) Thank you.
buying 3 domains is good if u can target 3 different sets of keywords... Just for portals around the same keywords there is no point to buy new domains... Same domain with subdomains would do it better.
Yes, buying 3 domain is a good idea & promote it with its individual keywords. Try to buy domains with the keywords so, it will helps a lot
