Miles explains

5 of 6 in range is honest, not perfect. The biggest miss was August 2026 (+67%), the kind of month when one big site jumps. That’s why the range is wide.

Visits are up on a year ago (+250%), and the last three months were higher than the three before. Name searches are up (+6% since October 2025). Recent months are getting stronger, and the forecast follows them.

+9.5% a month; the forecast carries part of the slope, fading

Miles explains

Big green or red bars are usually one site winning or losing a Google ranking, not the whole market moving. What I watch is the last three months against the three before: +78%.

November is usually a bigger month than average (21% above) for searches for “ai pdf reader”. But the sites’ visits follow rankings more than the calendar, so the pattern is shown and not allowed to move the numbers.

Used in this forecast?

No: average miss 14% as chosen, 14% without the pattern, 18.5% always with it

Miles explains

I tested the calendar against the last months and it made the forecast worse (18.5% average miss with it, 14% without), so I show it but leave it out.

About 1.0B visits in November 2026, up 4% on October 2026. The likely range is 951M to 1.1B.

By May 2027 the forecast expects about 1,102,564,775 visits a month, +11% on the 997,818,596 of October 2026, so the next six months look like growth.

The forecast expects ChatGPT (+4%), PDFgear (+4%), Foxit (+6%) and UPDF (+4%) to rise, and ChatPDF (-6%) to fall; the rest are within 3% of October 2026. Single sites are harder to forecast than the whole market, so their ranges are wider.

The ten site forecasts add up to 1,036,180,387, more than the market forecast of 1,034,095,614 for every tracked site. Each site is forecast from its own months, with the weighting and the seasonal pattern that suited that site best, and the market from the total, so the two need not add up: Foxit and UPDF are forecast with the seasonal pattern for November 2026, which the market forecast does not use this month. Read the site figures one at a time, not as a sum.

Miles explains

Foxit has the biggest expected rise (+6%). Single sites are much harder to call than the whole market, so read these as direction, not promises.

What could knock November 2026 off course:

• A big site winning or losing a page-one position for “ai pdf reader”.
• A Google update.
• A site going offline.
• A news story that spikes interest for a week and then fades.

None of these are in the numbers until they happen, which is why the range exists.
