Hi There, I've been offline a long time and right now I am trying to get myself together and work on my company website and rank as high possibly in SERPs. I would need advice with a couple thighs: 1. What SEO tools are you guys using, keyword research, etc? I am willing to go premium with tools if they worth the money, but I won't say no to free ones either. 2. Is it worth it building you're own PBN? 3. As a business website, my website won't have lots of content, should I add a blog to it? 4. If using many services form here such as PBN ones, should I be afraid of being penalized?
