What should B2B
SEO cost you?

For B2B and SaaS companies the working range is $3,000 to $20,000 a month, and most serious programs sit between $5,000 and $10,000 plus a separate link acquisition budget. Below about $3,000 you are buying one junior person executing a template, which in a competitive category produces nothing you can attribute. Above $20,000 you are usually buying embedded capacity or an enterprise program with several workstreams running at once.

The monthly fee is similar. What differs is where the money goes. B2B budgets skew toward fewer, deeper pages and subject-matter-expert interviews, because the reader is an expert evaluating a serious purchase and generic content fails immediately. B2C budgets skew toward volume and technical scale. A B2B program publishing four excellent pages a month will usually beat one publishing twenty average ones, which is not true everywhere in consumer search.

Same range as B2B generally, $5,000 to $18,000 a month all in. SaaS has one cost driver others do not: the product itself creates rankable surface area — integration pages, template libraries, docs — and building that properly needs engineering time you should budget separately from the retainer. On the other hand SaaS categories often have very winnable comparison and alternative queries, so the first commercial results tend to arrive faster than in, say, industrial B2B.

Work bottom-up rather than from a traffic target. Estimate how many commercial pages you will publish, how many organic sessions each earns once mature, the rate at which those sessions become opportunities, your close rate, and your average contract value. Multiply through and phase it across the year according to when each page ships and how long that page type takes to rank. The calculator above does exactly this. Comparing that against total spend including link budget gives you a payback month, which is the number a finance team will actually engage with.

For most mid-market B2B companies, somewhere between month five and month twelve. Bottom-of-funnel commercial pages — comparison, alternative, use-case — typically start ranking in 8 to 14 weeks, and those are what produce the early revenue. Broad category terms take 6 to 12 months. If a proposal promises payback in month two, ask what happens in month fourteen.

In an uncontested niche, $1,500 a month is enough. In a moderately competitive B2B category, budget $3,000. In something like CRM, project management or cybersecurity, $5,000 and upward, and expect that to buy nine to fourteen genuinely earned editorial placements rather than fifty directory listings. Treat it as a separate line from agency fees, because mixing them makes it impossible to see what you are paying for strategy versus placement.

Below about fifty customers, often zero. You do not yet know who buys or why, so any keyword research is guesswork dressed up as a spreadsheet. Get the technical foundation right once, write the comparison and pricing pages nobody else will write about you, and put the money into finding product-market fit. Once you have an average contract value above roughly $5,000 and someone who can approve a page inside a week, $5,000 a month starts to make arithmetic sense.

A report, some keyword rankings for terms nobody searches, and a few directory links. At that price nobody can afford to talk to your sales team, interview your engineers, or open a pull request. It is not that cheap SEO is bad value — it is that the fixed cost of understanding a B2B product well enough to write about it credibly is higher than $500 a month, so what you receive is work that skipped that step.

A senior in-house SEO lead runs roughly $130,000 to $180,000 fully loaded in the US, and cannot personally write content, build links and do technical implementation at the same time. A strong freelancer at $4,000 to $7,000 a month beats a mediocre agency easily, with capacity and holidays as the risk. The split that works most often is in-house owning writing and product knowledge, external owning strategy, technical and links — each side doing the part where it has a real advantage.

The cost side is exact, since the prices are published. The return side is a model, and in the first six months it carries roughly 40% error either way. The assumptions that break most often, in order: publishing capacity turns out lower than planned because of review bottlenecks, search demand in narrow categories is smaller than keyword tools claim, and competitive difficulty is understated by difficulty scores. Every assumption in the model is listed below the calculator so you can argue with the specific one you disagree with.

The mix changes more than the total. The first two quarters are heavy on technical work and building commercial pages. After that, a growing share of the budget shifts to refreshing what exists, which is cheaper per unit and often produces better returns than new content. Some clients step down a package once the build phase is done and the work becomes maintenance. Stopping entirely is the expensive move — most of a program is lost within a year of pausing it.
