Before the emergence of ChatGPT, brainstorming blog topics for your plumbing website was a challenge.
Today, AI and large language models can produce thousands of potential blog topics in mere seconds.
Unfortunately, haphazardly publishing posts based on these AI-generated topics can harm your website’s rankings on Google.
Nolen’s Key Takeaway
When I first started Plumbing Webmasters back in 2011, blog posts would rank easily on Google. Today, in 2025, blogging is largely an obsolete SEO tactic.
Plumbing Webmasters performs content writing services for hundreds of plumbers nationwide.
With a decade-plus worth of keyword research data, we can provide a trustworthy list of blog topics that can generate traffic on Google.
However, we strongly urge you to consider other SEO tactics instead.
Based on our internal agency data, we present 102 plumbing blog topics you can use for your website.
We also include the target keyword volume to indicate the post’s potential reach in hopes of boosting your plumbing content in 2025.
You can use these topics for your plumbing company blog to increase traffic, engagement, and rankings, though we strongly recommend utilizing more modern approaches.
Note on Zero-Volume Blog Topics
Although keyword research tools may assign “zero” search volume to a given blog topic, it does not mean that a blog post targeting the query won’t receive any traffic.
In fact, blog topics targeting zero-volume search queries often attract significant traffic from search engines, especially if they provide a unique perspective on a topic that is not currently available on other websites.

How Long Should My Blog Posts Be?
The highest-ranking blog posts typically range from 1,000 to 2,000 words in length. However, Google has publicly stated that word count is not a ranking factor.
Furthermore, Google values user experience, and most users want to see an answer immediately after clicking on the search result.
With this in mind, make sure to include a “key takeaway” or “summary” section near the top of your post so that you can provide a concise answer to the fundamental question of the post’s topic.
Where Should I Link My Blog Posts?
Link to the most relevant service page based on the topic.
For example, link to your slab leak repair service page if you are writing a post about slab leak symptoms. This way, you move blog readers through a funnel to becoming a plumbing client.
How Frequently Should I Publish Blog Posts?
Publishing frequency is irrelevant. The goal of blog posts is to increase organic traffic from Google and serve as social media and email marketing content.
Therefore, there’s no set number of posts you should publish per week or month. Instead, try to rank for as many relevant keywords as possible.
Final Thoughts on Plumbing Blog Topics
In its traditional sense, blogging is no longer an effective promotional technique for plumbers. Nobody is going to bookmark your plumbing company blog and check out every newly published post.
However, with the right blog topics, posts can still contribute to topical authority. The key is publishing optimized posts that target a specific keyword and topic.
These posts can rank on Google search results and bring in organic traffic.
