The short version: a blog is a website (or part of one) where someone writes articles on purpose, on a topic, on a schedule they can keep. That is it. Blogging is the act of writing and publishing those articles regularly, usually to build an audience, sell something, or both. Everything else you read about SEO, monetisation, and “passive income” comes after that basic bit clicks into place.
Blogging, stripped of the jargon
I have been writing online since 2009, back when “blog” still sounded like a made-up word your teenager used. Seventeen years later, people still ask me the same question at conferences and dinners: “So what is a blog, then?” Not what makes a blog successful. Not how to monetise one. Just what it is.
Here is my honest answer. A blog is a section of a website that gets updated regularly with written posts, usually shown newest first, usually on one broad topic (marketing, gardening, parenting, dog training, whatever). Each post has a title, some text, maybe a photo, and a date. That is the entire mechanical definition. WordPress, Wix, Squarespace, Substack, Medium, it does not matter which platform, they are all just tools for doing the same simple thing: putting words on a page and giving that page an address on the internet.
The word itself comes from “web log,” shortened in the late 1990s by a man called Jorn Barger, who used it to describe his own list of interesting links he found while browsing. You can read more about the history of the term on Wikipedia’s blog page if you want the full timeline. But the short story is: people started keeping online diaries and link lists, someone shortened “web log” to “blog,” and by 2004 it had become a proper noun for an entire way of publishing.
What a blog post looks like
Picture a physical noticeboard outside a shop. Every week the shop owner pins up a new note: “we’ve restocked the good coffee,” “here’s how to store your bread so it lasts longer,” “we’re closed Tuesday for a family thing.” Each note is dated, each one is short, and regular customers walk past and check what’s new.
A blog post is that noticeboard note, except online, and anyone in the world can walk past. A typical post has:
- A headline that says what it is about
- An opening paragraph that hooks the reader in the first few seconds
- The main content, broken into sections with subheadings
- Maybe an image, a list, a quote
- A publish date and often the author’s name
That structure has not changed since I started. What has changed is length and intent. In 2009, a “good” blog post was 400 to 600 words and mostly just personal opinion. Now, a competitive post on a subject like this one runs 1,500 to 3,000 words because search engines and readers both want depth, not fluff.
Why people start blogs
The reasons haven’t changed much in seventeen years, but the mix has:
- To build authority in a niche, so people trust them enough to buy from them or hire them
- To get found on Google for questions their future customers are typing, which is called SEO traffic
- To document a journey, like a small business owner sharing what they’re learning as they go
- To make money directly through ads, affiliate links, sponsored posts, or their own products
- Just to think out loud, purely for themselves, with no business goal at all
Most successful business blogs mix the first two. My own blog exists mainly so that when someone types “AI consultant for small business UK” or “how much does an AI consultant cost,” they land on something I wrote rather than a generic listicle with no lived experience behind it.
A quick, real example
Here is the bit most beginner guides skip because it makes blogging look less magical than they’d like it to.
In 2011 I wrote a post about using Twitter for small business, back when Twitter still felt new and exciting. It took me about 90 minutes to write, 800 words, no strategy behind it beyond “this is what I’m doing and it’s working.” That single post got picked up by a marketing site, then shared by a few people with big followings, and within a fortnight it had brought in roughly 3,000 visitors and two actual paying clients. I remember checking my analytics obsessively that week like it was a lottery ticket.
Here is the uncomfortable part nobody tells beginners: that post worked because of luck and timing, not because I followed a formula. I wrote roughly 40 other posts that same year that got almost no traffic at all, some under 50 views total. That is the normal ratio for most bloggers, even ones who know what they are doing. Blogging is not a machine where you put in 800 words and get out visitors and sales. Most posts, even good ones, sit quietly and do very little. The ones that work tend to be the ones you least expect, and you only find out which they are after you have published a lot of them.
If anyone promises you that blogging is a reliable, predictable route to traffic or income, they are either selling you a course or they have not run a blog for more than a year.
Blogging versus other types of online writing
People muddle blogging up with a few other things, so let’s separate them:
- A blog is not a website. A website is the whole structure (homepage, about page, contact page, shop). A blog is usually one section of that website, though for some people the blog is basically the whole site.
- A blog is not social media. A LinkedIn post or a tweet disappears into a feed within hours. A blog post sits on your own website, keeps working for years, and can be found through Google search long after you published it. I still get traffic on posts I wrote in 2014.
- A blog is not a newsletter. A newsletter goes to people who already subscribed, straight into their inbox. A blog is public, sitting on the open web, findable by strangers who have never heard of you before they searched a question.
- Blogging is not the same as copywriting. Copywriting sells something directly, right now. Blogging usually informs or entertains first, and sells later, or not at all in that particular piece.
How a blog makes money (or doesn’t)
This is where beginners get their expectations wrong most often, so let me be blunt about the real numbers.
There are four common ways bloggers earn:
- Display ads, where you get paid per thousand views. Small blogs with a few thousand monthly visitors might earn $5 to $20 a month from this. It takes hundreds of thousands of monthly visitors before ad income becomes a proper wage.
- Affiliate links, where you recommend a product and earn a commission on sales. Amazon’s affiliate rates run from about 1% to 10% depending on category, which is why niche product review blogs often need tens of thousands of visitors before this pays real money.
- Selling your own product or service, which is what works fastest for most small business owners. My blog does not run ads. It exists to get people to my consulting work and my talks. That is the honest business model behind most business blogs you read, even the ones that look purely informational.
- Sponsored content, where a brand pays to appear in a post. This only becomes realistic once you have a genuine, engaged audience, usually tens of thousands of readers a month.
If your goal is money, understand this before you start: a brand new blog typically earns nothing for the first six to twelve months, no matter how good the writing is, because search engines need time to trust a new site and readers need time to find it repeatedly before they act. If you want a broader list of realistic income routes while your blog builds up, my guide on 51+ real ways to make money online covers other options you can run alongside blogging in that quiet early period.
How to start one: five steps
Enough theory. Here is what I would tell a friend sitting at my kitchen table asking how to begin this week.
- Pick a topic you can write about for two years without getting bored. Not a “niche,” just a subject you already know something about. Mine is marketing and AI because that is my actual job.
- Get a proper domain and hosting. WordPress.org with hosting through a company like Bluehost or SiteGround costs roughly £3 to £10 a month. Avoid free platforms like Wix’s free tier or Blogger long term, because you do not fully own the site or the audience data.
- Write your first ten post titles before you write a single word of content. This stops the blank page problem and shows you fast whether you have enough to say on this topic.
- Publish weekly for three months minimum before judging results. That is roughly 12 posts. Anything less and you have not given search engines or readers enough to notice a pattern.
- Check your analytics monthly, not daily. Daily checking with a brand new blog will just depress you, because the numbers are small and slow for a long time. Monthly checking shows you the actual trend.
Common beginner mistakes I still see
- Writing about everything instead of one clear topic, which confuses both readers and Google
- Publishing once, then disappearing for three months, then wondering why nothing happened
- Copying someone else’s successful post structure without adding a single fact or experience of their own
- Obsessing over the “perfect” design before publishing a single word of actual content
- Expecting income within weeks, which almost never happens even for skilled writers
The single biggest mistake, though, is treating blogging as a content task rather than a relationship task. Every post is a conversation with one specific reader who typed a specific question into Google at 11pm. Write for that one person, not for an imaginary audience of thousands.
Frequently asked questions
Is blogging still worth starting in 2026?
Yes, but the bar is higher than it was ten years ago because there is far more content competing for the same searches. It still works well for building trust and getting found on Google, especially for small businesses writing about their own specific expertise, but it takes longer and requires more real depth per post than it used to.
Do I need to be a good writer to start a blog?
No. You need to be clear and specific, which matters far more than fancy sentences. Some of the most successful blog posts I have written were plain, almost conversational, because that is what makes a stranger trust you enough to keep reading and come back.
How long does it take before a blog gets traffic?
Most new blogs see very little search traffic for the first three to six months while Google works out whether the site is trustworthy and consistent. Real, steady traffic growth usually shows up between six and twelve months in, and only if you have published regularly during that time, not just once or twice.
What’s the difference between a blog and a vlog?
A blog is written content on a webpage. A vlog is the video version of the same idea, usually hosted on YouTube rather than a personal website. Some people run both, using the blog post as the written script or summary for the video, which also helps the content get found in text-based search results.
