The short version: “Blog post” is two words in standard English, always has been, and “blogpost” as one word is still considered nonstandard by every major style guide and dictionary. Use “blog post” in your writing unless you’re deliberately matching a brand name or a specific in-house style sheet that says otherwise.
I get asked this more than you’d think, usually by someone mid-draft who’s just typed the phrase eleven times and suddenly can’t remember if it’s one word, two words, or hyphenated. Fair enough. English does this to us constantly. “Email” used to be “e-mail” with a hyphen until enough people got tired of typing the hyphen and dictionaries caved. “Website” started as “web site.” So the confusion is reasonable. It just isn’t correct in this case, and I want to save you the fifteen minutes I once lost checking three different style guides mid-deadline over exactly this.
The actual answer, no hedging
Blog post is two words. Full stop.
The Associated Press Stylebook treats it as two words. The Chicago Manual of Style, which I lean on for most long-form client work, agrees. Merriam-Webster lists “blog” as its own entry and doesn’t recognise “blogpost” as a compound word at all. Cambridge Dictionary does the same. If you search for it, you’ll find “blog post” used as two words in the New York Times, the Guardian, and pretty much every major outlet that publishes about the internet, media, or writing.
Compare it to words that did earn compound status: “website,” “email,” “podcast.” Those went through a slow merge because the two-word version was clunky and the single word won out through sheer repetition over fifteen to twenty years. “Blog post” hasn’t gone through that same shift, even though “blog” itself is already a shortened form of “weblog.” The compound version, “blogpost,” shows up constantly in casual writing, in Slack messages, in briefs from clients who are in a hurry, but it hasn’t been adopted by the institutions that decide these things. Not yet, and possibly not ever, because unlike email or website, there’s no functional reason to merge it. Nobody’s typing it fifty times a minute the way we used to type “e-mail.”
Why so many people write it as one word anyway
Here’s the part other grammar guides tend to skip over because it doesn’t fit neatly into a “right versus wrong” framing: a huge number of professional bloggers, marketers, and even some agencies write “blogpost” constantly in internal documents, and it doesn’t hurt them commercially. I’ve seen briefs, invoices, project management boards, and even published client work using the single-word version, and readers rarely notice or care. Grammar purists will tell you it’s always wrong to use it. Commercially, in a Trello card or a Slack thread, it makes zero difference to anyone’s bottom line. The uncomfortable truth is that correctness and consequence aren’t the same thing, and most of the internet has quietly decided this one doesn’t carry much consequence.
That said, there’s a real difference between internal shorthand and anything that goes out under your name or your brand’s name. If you’re publishing on your own site, pitching a guest post through guest blogging outreach, or sending a piece to an editor, “blogpost” as one word will read as a small but noticeable slip. Editors notice these things. I’ve had guest pitches rejected for smaller issues than that, not because the idea was bad but because sloppy mechanics signal a sloppy writer before anyone’s even read your argument.
The one exception worth knowing
There’s exactly one situation where “blogpost” as a single word is fine, and it’s when you’re referencing a specific brand, tool, or platform that has built the compound into its own name or product. Some CMS plugins, some SaaS dashboards, and a handful of niche publishing tools use “BlogPost” or “blogpost” as a feature name or a menu label. If you’re writing documentation or a review that references that exact product name, you match their spelling. Outside of that narrow case, default to two words every time.
Hyphenating it, “blog-post,” is its own separate mistake and one I see less often but it does happen, usually from writers who assume any compound-sounding phrase needs a hyphen the way “well-known” or “long-term” do. It doesn’t. There’s no style guide anywhere recommending the hyphen for this one.
A quick story from a client deck
A few years ago I was reviewing a content calendar for a small SaaS client, maybe eight people on the marketing side, and their internal template had “Blogpost Title” as a column header across dozens of rows. Nobody had ever queried it. It had been copied from an old template built by someone who’d since left the company, and it had just propagated for two years across every planning doc they touched. It didn’t hurt their published output because their editor caught and fixed it before anything went live, but it meant every single planning meeting for two years had this tiny inconsistency sitting in plain sight, and it took a new hire on her first week to point it out. Small thing. Zero commercial damage. But it’s a decent reminder that these habits creep in through templates and spreadsheets far more than through anyone consciously deciding to spell something a certain way, and they stick around until someone new happens to notice.
How to remember it for good
If you want a rule that sticks without needing to check a style guide every time, use this: treat “blog” the same way you’d treat “news.” You wouldn’t write “newspost” as one word, you’d write “news post.” Same logic applies here. “Blog” functions as a modifier, not a prefix that’s fused into the noun that follows it. That mental trick has saved me more autocorrect arguments than I can count.
If you’re proofreading your own work regularly, tools like Grammarly will flag “blogpost” as a likely error, though it won’t always explain why, which is part of the reason I wrote about how Grammarly built its brand around exactly this kind of small, constant correction. It’s useful as a second pair of eyes, not as a replacement for knowing the rule yourself. And if grammar precision is something you enjoy rather than dread, there’s a whole freelance path in it. I wrote a full guide to proofreading jobs for people who love grammar that covers what it pays and where the work comes from.
Where this fits into the bigger picture of writing well
None of this matters much on its own. Nobody’s losing clients over one compound word. But readers and editors form quick impressions from small details, and a string of small details, “blogpost,” “alot,” missing serial commas, stacks up into a general sense that the writing wasn’t cared for. If you’re building a habit of writing consistently, whether that’s for your own site or for guest pitches, it’s worth having a short mental checklist of these little traps. I keep one for myself, and “blog post” sits right near the top because I typed it wrong for years before someone finally corrected me in a comment thread, publicly, which is its own kind of memorable lesson.
If you’re writing blog posts regularly and want to speed up the drafting without losing the small grammar details that matter, it’s worth looking at where AI tools help versus where they just create new inconsistencies to catch. I cover the tools I use, not the ones I’m paid to mention, in my rundown of AI writing tools for bloggers. And if you’re setting up a blog from scratch and want the basic kit sorted before you worry about grammar at all, my piece on the tools to launch your blog like a pro covers that groundwork. If you’re doing all of this from your phone because that’s how your schedule works right now, I’ve also written honestly about blogging from a mobile phone and where that setup falls apart.
Frequently asked questions
Is it blog post or blogpost in AP style?
AP style treats it as two words, “blog post,” and does not recognise “blogpost” as a standard compound.
Does Merriam-Webster recognise blogpost as one word?
No. Merriam-Webster lists “blog” on its own and does not have a compound entry for “blogpost,” which means “blog post” is the dictionary-backed spelling.
Is blog-post with a hyphen ever correct?
No major style guide recommends hyphenating it. The correct standard spelling is two separate words with no hyphen, “blog post.”
When is it okay to write blogpost as one word?
Only when you’re matching an exact product name, menu label, or brand term that has built the compound into its own naming convention. Outside that narrow case, two words is always safer.
