One Line A Board Could Publish

Two numbers, printed next to the filter panel, would tell every reader exactly what the board can and cannot separate. It costs a line and gives up nothing.

A board could print two numbers beside its filters: how many kinds of listing it can tell apart, and how many different questions it permits.

That is the whole proposal. It costs one line, it reveals nothing competitive, and it would change what readers can know about a board more than any other single change available.

For work that changes shape during the week, managers can view the official product information and review task-level context rather than a single total. For a separate technical reference, see U.S. Census Bureau.

What one line would say

the upright: where this figure falls on the record's range
the ticks are powers of ten; the scale is logarithmic

Two figures placed; the range is the record's own, over cells and queries.

The pair for a board of three filters offering four, six and six choices, placed on the record's two ranges. Both figures are computable from the sidebar in a minute.

Placed on the full range the record holds. The scale is the record's own, and the drawing refuses a scale that is not.

What it would tell a reader

Whether their search failed or the board did. Somebody who cannot separate two listings currently has no way to tell whether they phrased the query badly or the board carries no filter for the difference. The resolution settles it: if the two listings agree on every filter, nothing will separate them, and the reader can stop trying.

What narrowing is available. Knowing the question count tells a reader how much expressive room there is before they start.

Whether two boards are comparable. Two pairs, four numbers, and the structural comparison is finished.

The information is already on the page. It is simply spread across a sidebar in a form that requires multiplication, and most people do not multiply sidebars.

Where it would go

Beside the filters, in a line.

Not in a help page, not in a footer, not in documentation nobody opens. The figures describe the panel, so they belong next to the panel, where somebody deciding whether to keep narrowing can see them.

A line of a dozen words, updated when the filters change, which is rarely. There is no engineering here and no design problem; there is only the fact that nobody has done it, which makes the first board to do it look eccentric rather than candid.

Why nobody does it

Not secrecy. Three plainer reasons.

Nobody computes it internally either. The figures are not on anybody's dashboard. A board knows its listing count and its traffic; the resolution is not a number that gets produced in the ordinary course of running one.

It looks like a small number. One hundred and forty-four is not an impressive figure to print next to a board carrying forty thousand listings, even though it is the more honest description of what the board does.

There is no convention for it. No other board publishes it, so publishing it reads as odd rather than as transparent.

The second reason is the real obstacle, and it is worth naming plainly: the honest figure is less flattering than the figure boards currently quote, which is how many listings they hold.

What it would not cost

Anything competitive. The figures are derivable from the page by anybody who cares to multiply, so publishing them discloses nothing that was hidden.

Nor would it constrain the board. The figures change when the filters change, which is a deliberate act, and updating a line of text is the smallest part of making a schema change.

What it would change over time

Comparison on a basis that holds.

Boards currently compete on listing counts, which are a statement about this week and are gameable in several obvious ways. A board competing on resolution would be competing on something it cannot inflate without actually improving the structure.

Figure quoted	Can be raised by
listings held	volume, duplicates, stale entries
resolution	adding or widening filters, and nothing else

The second column is short, and everything in it is a real improvement to what readers can do.

What a board would have to accept

That its resolution is smaller than its listing count, usually by a lot.

A board with forty thousand listings and one hundred and forty-four cells is, on average, putting two hundred and seventy-seven listings in each compartment. Publishing the resolution makes that visible, and it reads as an admission.

It is not one. Two hundred and seventy-seven listings in a compartment is what happens when a board has many listings and a reasonable number of filters, and no board of that size avoids it.

What publishing the figure changes is that readers stop assuming the filters can do more than they can — which is the assumption that sends somebody clicking through variations of a query that was already as narrow as the board allows.

The version for somebody who does not run a board

Compute it yourself and write it down.

The procedure is four steps and a minute, and the page on reading a sidebar sets it out. Nobody needs the board's cooperation: the figures are a property of what is already published, and the only reason they are not common knowledge is that the multiplication happens to be nobody's job.

Doing it once for the two boards somebody is choosing between settles, permanently, a question that otherwise gets decided on which sidebar looked busier.
