Press or news releases about industrial products have been and still are very popular. They work because the content is mainly about features that help engineers specify these industrial products.
In the past, manufacturers used them primarily in traditional print media like an industry-specific tabloid. People sent back a completed reader service or bingo card and leads were generated that way. Of course, those days are long gone. Today, you are more likely to see a URL like http://ogpe.hotims.com or http://powereng.hotims.com printed at the end of the news release.
Since industrial companies struggle with content, I think one way to overcome the problem is to take a traditional marketing tactic like a news release and turn it into a blog post for use in digital marketing.
What I’m suggesting here is not to copy word-for-word from your old product releases but to expand on them and create new blog posts. Instead of listing product features and specifications, your blog posts can add a lot more information, which will be more educational rather than a blatant sales pitch.
