DIY, in-house
You or someone on your team monitors the source platforms, writes the pitches, and chases placements. It costs no money beyond platform fees, and nobody knows your expertise better than you do. The catch is time: winning links this way is a daily habit, not a one-off task, and most in-house teams drop it within a month because the deadlines never stop.
Best for founders with genuine expertise and a few hours a week to spare.
