Where these numbers come from

For each keyword we compare the mean volume of the last three months with the mean of the same three months twelve months earlier. That is its year-on-year growth.

But we do not rank on raw growth, and the reason came out of the measurement itself. A severe dip sits under all Persian search around March 2026: five keywords from five unrelated industries all fell together in the same months, and for most keywords Google returns that month empty. Rank on raw growth and every row turns red, so a page meant to show what is rising shows nothing but decline.

So each keyword is measured against the median of the whole corpus in its language. That is what the "growth vs market" column means: how far ahead of or behind the market median this keyword ran. A zero means it moved exactly with the market, not that it stood still.

The current median of this corpus is -2.6, computed from 391 keywords that had a calculable growth figure.

This section does not discover new keywords. The only product that finds emerging queries is Google Trends related queries, and for Persian it returns an empty list at every location we tried. So we build the corpus ourselves and then measure it, and nothing here claims to have found a trend on its own.

Volumes are Google estimates, not our count. Google itself reports them in rounded buckets, so two keywords showing the same number are not necessarily identical in size.

The five-year chart is a 0 to 100 index, not an absolute number. It is scaled to the highest point of that same chart, so two different charts cannot be compared with each other. Absolute figures exist only for the last twelve months, and those are what the volume column and the monthly bars show. A five-year absolute chart does not exist for Persian and we do not manufacture one.

Momentum and seasonal peak stay empty when a keyword series does not carry enough resolution. That is deliberate: on a flattened series any ratio produces a number that looks like a measurement and is not one.

And one warning about reading momentum: a seasonal keyword shows high momentum in its own season. Villa rental climbs every summer and falls every winter, and that is not growth. This is why the seasonal peak sits next to it.

For each sector we give two or three seed terms and Google returns hundreds to thousands of ideas, each with its own volume. The highest-volume ones become the list. So measurement decides the final list, not our opinion.

There is an intermediate step without which the list would be meaningless. Google returns the spelling variants of a keyword with the same volume attached; in one real sample eight different spellings of one Turkish phrase all came back with an identical number. Take the top twenty-five naively and the list becomes about eight real queries and seventeen spellings of those eight. So variants are collapsed into one row, with the count shown beside it.

That merging is tuned conservatively. Two keywords are treated as one only when their reported volume is exactly equal and their spelling is close. When in doubt they stay apart: two near-identical rows are better than one row that presents two different things as the same.

Volumes come from Google Ads with a language filter and no country filter, so this measures English-language demand worldwide rather than any single market.

The data is refreshed monthly. The last measurement date at the top of each page is the real date the measurement ran, not the date the page was published.
