In a b2b company, have identified few intent based keywords vol is quite low, still struggling to rank.

Been at it for 2 months, we have a SaaS product for which I've identified 5 main kws that I want to rank for. Have created a product page but struggling to rank.

Don't have backlinks yet. Have few internal links.

What should I do next? Should I write more value based blogs around that keyword? How to make sure Google doesn't rank the blog over product page?

Would appreciate help.
