Hi! I've been reading a lot about SEO in the last two months, everything I could. I've learnt to perfectly dominate keyword reseach, competition analysis and on page optimization. However, I'm stuck regarding to link building. In the next days I'll open a company about web design, online shop design, PPC services... I would also like to offer SEO services in my country. I need to know the best and safest method to get my business page and then my clients pages to top positions in Google. I've thought in these strategy: For my site: I should use a safe method to not get penalized. Do you think the most powerful method is to manually make a PBN for TIER1 with expired domains and then, for TIER2 use SAPE links that I buy from BHW? Another option could be only use a TIER1 with my OWN PBN. What do you think is the best and safest method for my business site? For my clients: I think of using a BHW service of SEOsolutions (they use SAPE) and with buffers for TIER1. My clients will pay a monthly fee, if they don't pay, links are removed. Do you think I'm doing good? Please I need some advice. I'm from Spain. Thanks.
