Look at the CPC column on almost any THC keyword in Ahrefs. It says N/A.
That is not a data gap. Google does not accept ads for THC products, so there is no auction, no cost per click, and no way to buy your way onto the page. For a cannabis brand, organic search is not the cheapest acquisition channel. It is close to the only one that scales.
This client came to us in April 2022 with 13 pages ranking for anything at all and 428 visits a month.
Where they started?
Three keywords in the top three positions. Zero in positions four to ten. Six in positions eleven to twenty. A total of 190 ranking terms across the entire domain, of which 114 sat past position 51 where nobody has ever clicked anything.
Domain Rating 43, on 537 referring domains. For an e-commerce site selling into a category where every competitor is fighting for the same unpaid real estate, that is a starting hand, not a position.
What we built?
1300 placements between April 2022 and July 2025. Guest posts and insertions into already-published pages. No content, no technical work.
Referring domains went from 537 to 6,557. Domain Rating went from 43 to 72.
That DR figure deserves a moment. The scale is logarithmic, so 43 to 72 is not “29 points.” Each point above 60 costs multiples of what a point in the forties costs, and a DR 72 domain in cannabis sits above most of the category’s venture-funded brands.
What it produced?
| April 2022 | July 2025 | |
|---|---|---|
| Organic traffic | 428 | 101,431 |
| Ranking keywords | 190 | 60,934 |
| Positions 1 to 3 | 3 | 2,662 |
| Positions 4 to 10 | 0 | 4,734 |
| Pages ranking for anything | 13 | 350 |
| Referring domains | 537 | 6,557 |
| Domain Rating | 43 | 72 |
The traffic line is the number everyone quotes, and it is the least interesting row in that table.
Look at positions four to ten instead. It went from zero to 4,734. In April 2022 this domain held not a single first-page position outside the top three, which is what a site looks like when Google has no reason to trust it on anything. Three years later it holds nearly five thousand.
And 13 pages became 350. The site did not grow twenty-seven times bigger. Those pages mostly existed already, sitting unranked, waiting for the domain to earn enough authority for Google to bother indexing and ranking them.
The part a case study would normally crop
Traffic peaked around 180,000 a month in mid-2024. By July 2025 it was 101,431. That is a fall of roughly 44% from the high, and the chart you would see if we cropped this section ends on a downward slope.
We are not going to pretend that away. Cannabis is a volatile category in search: the SERPs get restructured, affiliate roundups get promoted and demoted, and regulatory pressure moves what Google is willing to surface. The authority metrics did not deteriorate over that stretch. Referring domains and Domain Rating both held. Something changed in how Google chose to display the category, and we would be guessing if we told you exactly what.
101,431 a month against a starting point of 428 is the honest number. The peak was higher, and the peak is not what we are claiming.
Where the site stands thirteen months later
We placed our last link in July 2025. Here is what the domain was doing in August 2026, with no further work from us.
| Keyword | Volume | Feb 2026 | Aug 2026 |
|---|---|---|---|
| weed pen | 66,000 | 73 | 15 |
| weed cart | 26,000 | 64 | 24 |
| weed pens | 24,000 | unranked | 16 |
| cart weed | 23,000 | 75 | 21 |
| disposable weed pen | 15,000 | 77 | 13 |
| weed vape | 14,000 | 72 | 16 |
| thc vape | 13,000 | 42 | 16 |
| disposable cart | 12,000 | 88 | 15 |
| thc pen | 12,000 | 71 | 17 |
| thc vape pen | 11,000 | 31 | 9 |
Position 88 to 15 on “disposable cart,” a term with 12,000 monthly searches. Position 73 to 15 on “weed pen,” which does 66,000.
On a separate set of higher-difficulty commercial terms the site now holds position one for “best online thc gummies” (KD 74), position one for “gummies that make you high” (KD 72), and moved from six to one on “hhc pens.” Several of those results carry AI Overview citations.
None of that movement happened during our engagement. It happened afterwards, on the link profile built during it.
The read
Link equity does not switch off when the invoice stops. It decays slowly, and while it decays it keeps buying rankings the client is no longer paying for. That is the difference between authority and traffic you rent.
For a cannabis brand the argument is sharper still, because the alternative channel does not exist. A firm selling legal services that dislikes its SEO bill can move the money to Google Ads and get clicks tomorrow at $45 each. A THC brand cannot. There is no auction to enter. Whatever organic position it holds is the position it has, and the only lever that moves it is authority.
Starting at 428 visits a month makes almost any percentage look absurd, so ignore the percentage. The number worth holding onto is 13 pages to 350.
