1. Plumbing Basics & Homeowner Education

These are typically “X vs. Y” style posts. But keep the language simple and avoid plumber talk.

1. Why Is My Water Bill So High All of a Sudden?

2. Routine Maintenance & Preventive Care

Most plumbing disasters don’t pop up overnight.

They’re the result of small, ignored issues that snowball over 12 to 48 months.

That’s your in! These next 10 posts target homeowners who neglected their plumbing and want to avoid digging themselves further.

5 Content Tips​ for Plumbing Blogging

Anyone can write a plumbing blog. Very few can get actual clients from their blogs.

The key difference is strategy.

We’re feeling generous 🙂 Here are 5 content tips to rank locally, keep readers engaged, and get them to click that big, shiny “Contact” button.

1. Think Local, Not Global
   Nearly 46% of Google searches have local intent. Mention your city, neighborhoods, and local issues (hard water, freezing temps). “Drain cleaning” should be “drain cleaning in [Your City]”.
2. Write for the Panicked Reader
   Most visitors are stressed. Don’t give them a history of porcelain. Get to the clogged toilet fixes ASAP. Users decide in 10 seconds if your page is worth it.
3. Use Photos of Your Jobs and Team
   No AI. No stock imagery. Please! Use before/after images to prove you do the work. Real images always outperform stock images in A/B tests.
4. Speak Like a Human
   Avoid jargon. If you say “P-trap,” explain it for the average person. Simple language keeps readers engaged and reduces bounce rates.
5. Use Lead Magnets
   Every reader has value. Don’t let them leave without taking the next step. Add tools like cost calculators, checklists, or “get an estimate” forms to keep them engaged.

This seems like a lot to do on your own. And we’ll be honest… it is.
