How to Value a Blog: A Step-by-Step Formula

Blogs are valued differently than they feel

To the person who built it, a blog feels like a body of work — hundreds of hours of writing, a voice, an audience. To a buyer, it's a cash-generating asset whose value comes down to how much money it makes, how reliably, and how easily someone else could keep it running. That reframing is the whole game: the more your blog looks like a predictable, transferable business rather than a personal project, the higher the multiple it earns. Here's the step-by-step process buyers use, so you can run the numbers the way they will.

Step 1: Average your last 12 months of profit

Blogs are seasonal — a recipe site peaks around holidays, a tax site peaks in spring — so a single strong month tells a buyer nothing reliable. Use a trailing twelve-month average of net profit, subtracting every real cost: hosting, email tools, plugins, writers, and design. This averaged figure is both more honest and more defensible, and it's the number a buyer will reconstruct from your statements anyway. Starting there yourself means no unpleasant surprises when diligence begins.

Step 2: Choose your base multiple

Most blogs trade around 34–40× monthly profit in the current market. Start in the middle of that range as your baseline, then move up or down based on the specific strengths and weaknesses below. Resist the temptation to start at the top 'because my content is great' — buyers price on evidence, not effort, and an inflated starting point just leaves your listing sitting unsold.

Step 3: Score your traffic quality

Not all traffic is worth the same. Organic search traffic spread across many keywords and many pages is the gold standard, because no single ranking change can sink the whole site. Traffic concentrated in one or two viral posts is fragile and gets discounted, as does traffic that leans heavily on a single referral source or social platform. Buyers will pull your analytics and look precisely at this distribution, so an honest self-assessment here tells you where your real multiple sits.

Step 4: Factor in how you monetize

A blog earning purely from display ads sits at the low end of the range, because ad income is volatile and outside your control. Layering in affiliate income, an email list, and especially a digital product moves you up, because each added stream makes the total more resilient and signals untapped upside a buyer can expand. A diversified blog doesn't just earn more — it earns a higher multiple on the same profit, which compounds into a materially larger sale price.

Step 5: Adjust for age and owner dependence

A blog with a multi-year track record reassures buyers that the earnings are durable, while one under a year old reads as unproven and prices lower. Just as important is how much the site depends on you personally: if the brand is your face and the process lives in your head, buyers worry the audience won't follow a new owner. Documenting your workflow and building a brand that isn't purely you are among the cheapest ways to lift your final number.
