Advertising landing pages: six campaigns, one promise each
Every paid campaign sends traffic to one of these six pages. Each page makes a single promise, carries one form, and is kept out of the search index on purpose — so the organic pages are never judged against ad copy.
The six landing pages
Twin Screw Extruder Price
What actually drives the number: torque class, L/D, pelletizing method, wear package.
Filler Masterbatch Line
85–90% CaCO3 at 350–1,500 kg/h — feeder discipline and wear package.
PET Recycling Line
Hold the IV, not just the output: drying, vacuum and die residence time.
Cable Compound Line
PVC, XLPE and HFFR on one platform — the changeover is a screw set, not a machine.
Lab Twin Screw Extruder
15.6–36 mm screw diameter, 25–50 kg trials, 3–7 day turnaround.
Turnkey Masterbatch Plant
Feeder to bagging: layout, machine list, commissioning, operator training.

Why these pages are not indexed
A landing page repeats one keyword and one promise, which is exactly what an ad needs and exactly what an organic page should not do. Keeping them noindex, nofollow prevents the two from competing for the same query, and keeps duplicate thin content out of the index. The organic equivalent of each page is listed below.
| Landing page | Organic page |
|---|---|
| Twin Screw Extruder Price | Machines by family |
| Filler Masterbatch Line | Filler masterbatch line |
| PET Recycling Line | PET pelletizing |
| Cable Compound Line | Cable compound pelletizing |
| Lab Twin Screw Extruder | Pilot twin screw extruder |
| Turnkey Masterbatch Plant | Masterbatch production line |
Campaign traffic is measured in Google Analytics 4 with UTM parameters; what the forms collect is described in the privacy policy.

FAQ
Are these landing pages indexed?
No - every page under /lp/ is deliberately noindex, nofollow. They repeat one keyword for one advertising campaign; the organic pages they would compete with are linked in the table above.
Where do the forms on these pages send enquiries?
Each form posts to the site lead endpoint and lands with the engineering team in Nanjing the same way as the main contact form - a named engineer replies within one working day.
How is campaign traffic measured?
Google Analytics 4 with UTM parameters per campaign; the lead endpoint also records the landing page, page URL and gclid so a lead can be traced back to the ad that produced it.
