プロのヒント

Track the long tail: most press releases generate 70% of their traffic and backlinks within the first 72 hours, but quality placements continue driving results for 6–18 months. Set up ongoing monitoring with Google Alerts and Ahrefs to capture delayed pickups and link-building value that appears weeks after distribution.

難易度:中級

The first press release is credited to Ivy Lee, who in 1906 wrote a statement for the Pennsylvania Railroad following a train crash — rather than covering it up, he distributed factual information to journalists. This transparency-first approach is still considered best practice 118 years later.
