Publishing volume is not a strategy
Four articles a month with no commercial relevance will not grow revenue. Content should map to questions your buyers ask on the way to a purchase decision.
Match the intent behind the query
If the results for a term are all comparison pages, a company blog post will not compete. Study what already ranks and produce something demonstrably more useful in the same format.
Link content to money pages
Informational content should route readers towards the service or product pages that generate revenue, with clear, relevant internal links.
