B2B SEO -- How do I compete?

Ill try and keep this short and to the point. I own a B2B service company. Most of the SEO advice I have received boil down to the following: * Its about links. Get the links. * Create remarkable content and be found * Build a network of influencer friends and ask them to share, and my favorite, * Find low competition keywords, with high intent Now, I know that all of these work because I have some of this in B2C (e-com). But in my B2B service niche, my competitors are behemoths. So, to use the advice from above, my competitors: * they spend so much money on links that the price is basically out of reach for my baby business. * they have massive content teams solely focused on creating remarkable content. And If I am honest... the content is really good sometimes. * All the influencers want to work with them because they are already big brands. and, * Honestly, I have never seen a low comp keyword that has high intent AND good search volume so I dunno about this one. **So my question is, for B2B SEO, how do small companies compete?** If the answer is "its a money game and you can't", so be it. But I would appreciate it if you game me sufficient context as to why your answer is what it is (i.e. - please not a one line answer, that will just create more questions :)! )
