**Find both figures and divide.** The single most productive check on any pricing page is to multiply the monthly price by twelve and compare it with the annual total. If they are equal there is no discount, whatever the page says — and we have found a vendor advertising a substantial saving beside an annual figure that was exactly twelve monthly payments, to the penny, on two separate tiers. If the page prints only one of the two figures, the discount cannot be verified at all, which is itself worth knowing before committing to a year.
**Establish the billing basis before comparing anything.** The figure in the largest type is frequently the annual rate expressed per month, not a price you can pay monthly. Many pages open already in their discounted state. Some sell no month at all — one vendor's pricing page does not contain the word 'monthly' even once. Comparing two tabs quickly is the reliable way to put one vendor's annual rate against another's monthly one without noticing.
**Normalise the unit, and then check the period.** A per-seat price is not a bill until you multiply by headcount; a per-credit price needs your consumption; a per-monitor price needs your endpoint count. And check what period each allowance is quoted in, because one ladder we read counts documents per month on its entry tier and per year above it — a jump that looks twentyfold and is really less than double once both are annual.
**Treat a claim and its arithmetic as two separate facts.** We have checked eight vendors' own discount claims against the figures printed beside them. Two were fabrications, two understated their own offers, three were accurate to a fraction of a point, and one honestly claimed nothing where nothing was due. The direction of error cannot be assumed, which means the claim is never a substitute for the division — and a vendor rounding against itself deserves the credit as much as one overstating deserves the scepticism.
**Ask what the smallest purchase is.** A low per-seat rate can carry a minimum that makes it the expensive option below a certain headcount, and on one ladder the tier named for individuals is dearer per seat than the team tier from three people onward. 'Starting at' means the published figure is a floor with no stated ceiling. And at least one product carries a required setup fee worth about half of everything you pay in the first year, which appears in no monthly comparison anywhere, including ours.
**Find the limit that will bind you, not the one advertised.** Free and paid tiers alike are capped on wildly different axes: storage while people are unlimited, a minimum interval between runs, seats, subscriber counts, the number of items and the length of each. The most generous plan on the dimension a vendor advertises is frequently the tightest on the dimension you would actually use, and one platform's deepest free tier removes the automations that are the reason to want it.
**Ask what happens at the ceiling.** Crossing a limit pauses the service at one vendor and adds a per-unit charge at another, and a third reserves the right to do either. One costs money and the other costs the thing you were trying to do. It is a genuine product difference, it is decided long before you reach it, and it is almost never part of a comparison.
**Read an absence as a finding, and notice which kind it is.** A quote-gated tier tells you where the self-serve product ends. A page you could not read tells you nothing about the vendor. A deliberate zero — one vendor states in words that it charges no monthly fee — is a price. Those are three different facts and they are frequently presented as one blank space.
**Be most careful where a page looks most complete.** The failures that mislead are the ones that render: a currency symbol with no figure after it, a plan card showing add-on prices but not plan prices, a volume selector pricing two of its nine rungs, a well-formed zero standing where a paid rate belongs. A page that publishes nothing sends you elsewhere; a page that publishes something wrong sends you to checkout.
**Finally, check that you are comparing alternatives at all.** A category groups products that do similar work and quietly implies they are substitutes. In one category we hold, the dearest vendor's cheapest plan costs about ten times the cheapest vendor's most expensive plan — the ladders never meet, and no buyer is choosing between them. Before trusting any ranking, look at the spread: a factor of two or three is a comparison, an order of magnitude is a directory.
A note on what we do with all this. Every price on this site resolves from a dated reading of the vendor's own page at build time, in your edition's currency — SE Ranking's core tier is $129 a month as you are reading it, and a different figure in the other two editions, because the vendor sets a different price in each. We do not convert currencies, we do not take figures from other comparison sites, and where a vendor was read in one market only we withhold the page from the others rather than show you somebody else's prices. That means our coverage is patchier than it could be, and we would rather be patchy than plausible.
