When Stack was in its early growth stage, our focus was on ranking high for productivity keywords that were important to us. Eventually, we launched our own NFT project, selling lifetime licenses as NFTs. This made it necessary to rank well for NFT-related keywords too. Keeping that in mind, I wrote several articles on both productivity and NFTs. While the main goal was to boost Stack's ranking for relevant keywords, I believe these articles offer some valuable insights for readers as well.
