I should say up front that I sell a blog. It's an $850 add-on to a Solo or Group build, and it would be very convenient for me to tell you every therapist needs one.
Most don't. Some really do. The difference has less to do with SEO than with whether you'll still be writing a year from now.
What a blog actually gets you
The biggest thing is more doors into your site. Your homepage can rank for something like “anxiety therapist in Lakewood.” It can't also rank for “is it normal to feel worse after starting therapy,” because that's a different question with a different answer. A post can. Every real question you answer well is another search you can show up for, and those searches tend to come from people who are close to booking.
It also lets someone hear how you think before they ever call. A person who has read two of your posts walks into the first session already knowing your tone, how direct you are, whether you swear. That's most of what people are trying to figure out from a website anyway.
And AI answer engines like pages that answer one specific question plainly. A good post is exactly that kind of page. When someone asks ChatGPT or Google's AI Mode a question in your specialty, a clear post on your own domain is the thing it can quote and link to.
What it costs you
Time, mostly. For most clinicians a decent post is two to four hours once you count the drafting, the second-guessing, and picking a title. At a session rate of $150 or more, a monthly post is not free, even if nobody sends you an invoice for it.
Then there's the abandoned blog, which I see constantly. A journal page whose newest post is from March 2023 tells a visitor something you didn't mean to say: maybe this practice isn't really taking people anymore. No blog is better than a dead one.
Generic posts also don't do much. “Five Tips for Managing Stress” is up against the Mayo Clinic, every hospital system in the country, and a few thousand other therapists who wrote the same post. You won't outrank them, and readers can tell when a post was written to fill a calendar slot.
One more, specific to this field. You can't write about clients, even heavily disguised, and anything that reads as clinical advice to a stranger needs some care. That's not a reason to skip it. It does make each post slower than it looks.
Who should have one
If you have a narrow specialty and real opinions about it, a blog pays off. Perinatal anxiety, religious trauma, misophonia, therapy for first responders, the more specific the better, because the questions people type into Google in those areas don't have a hundred good answers yet. Twelve posts in a year on questions your actual clients ask will do more than fifty generic ones.
It also helps if you like writing. That sounds obvious. It's the best predictor I've found of whether a blog is still alive eighteen months later.
If the idea of a monthly post fills you with dread, skip it. Seriously. You can always add one later.
Does Google punish a site that never changes?
Not in the way people worry about. Freshness matters a lot for searches about news and things that change week to week. It matters much less for “trauma therapist Denver.” A solid service page that hasn't been touched in a year can keep ranking just fine, and plenty do.
What actually hurts is drift. Fees from two years ago. An office you moved out of. “Now accepting new clients” on a practice that has had a waitlist since spring. A site that is quietly wrong reads as stale to people and to search engines, and no amount of blogging fixes that.
Keeping a site fresh without a blog
This is the part I'd actually do, blog or not.
Treat your service pages as living pages
When clients keep asking a question you didn't see coming, add the answer to the relevant page. When you start offering something new, give it its own page; on my Solo builds every specialty already gets one, and adding another later is a small job. A new, focused page is worth more than a post, because it's the page someone searching for that service should land on.
Keep the facts right
Fees, insurance panels, the states you're licensed in for telehealth, your address, whether you're taking new clients. Check them every few months. It takes ten minutes and it's the most common thing I find wrong on therapist sites.
Let the FAQ grow
A new question and a short, honest answer a few times a year. It adds real content, it's the format AI answers like to pull from, and it's much less work than a full post.
Use your Google Business Profile
For local searches this matters more than your blog would. Post an update when something changes, add a real photo of your office now and then, reply to reviews, keep holiday hours current. Google treats an active profile as a sign of an active business, and it's where a lot of “therapist near me” searches get decided before anyone reaches your site.
Tell Google honestly when something changed
When a page really does change, the lastmod date in your sitemap and the modified date in your structured data should change with it. Only then, though. Google has said it ignores lastmod on sites where those dates turn out not to match reality, so bumping every date every month to look busy just teaches it to stop listening.
Look at Search Console once a month
It shows the searches you're already appearing for, including the ones you rank badly for. If you're showing up on page three for something you actually do, that's your next page or your next FAQ answer. This is how I decide what to write here, for what it's worth.
Where I land
If you'll write once a month about your specialty for at least a year, get the blog. If you won't, don't, and put that energy into the list above instead. A site with sharp service pages and correct facts will beat a site with a blog nobody has touched since 2023, every time.
A dead blog says more about your practice than no blog ever could.
Not sure which one you are? Ask me. I'll tell you straight, even if the answer is the one where I don't sell you the add-on. If you want to see what Google currently thinks of your site first, start with a search on your own name.
