Best aluminum extruders in Canada, according to AI. The Prompt Group Research. https://thepromptgroup.com/research/aluminum-extruders/ca","limitations":"This is one collection day and two runs, which is a snapshot and not a trend. Answer engines vary run to run, and this set shows it plainly. The same anodizing question on the same engine, six minutes apart, returned two entirely different source lists: one with no Canadian company in it, and one built on Canadian institutions. Treat the ordering below about 3 percent as unstable. The question set was built around one manufacturer's capabilities, so it over-represents design support, one-stop fabrication and anodizing relative to the category as a whole. A company strong in those areas will look better here than a broader question set would show. Share of mentions measures presence in answers, not market share, revenue or quality. Nothing here says which supplier a buyer should choose.","methodology":[{"detail":"Fifty questions about custom aluminum extrusion, anodizing, CNC machining, finishing and design support, put to ChatGPT, Perplexity and Google AI Overview. Each question was run twice on each engine, producing 300 answers. All answers were collected for a Canadian location.","term":"The panel"},{"detail":"Seven of the 50 questions name Dajcor Aluminum in their text. The other 43 do not. We classify by reading the question text, not by the flag that ships with the question set: that flag marks six of the seven, and misses Does Dajcor offer design support for my extrusion project. Every category figure here uses the 43 unbranded questions only, and says so.","term":"Branded and unbranded"},{"detail":"Every time an answer names a company, that is one mention. Share is a company's mentions as a percentage of all 256 mentions collected on the 43 unbranded questions. It measures how much of the conversation a name takes, not how many buyers would choose it.","term":"Share of company mentions"},{"detail":"The percentage of answers to a given question that name the company in question. A question scores zero when no answer to it named that company in either run.","term":"Visibility"},{"detail":"A citation is one reference to one URL inside one answer. Domains are counted across all 300 answers, including the seven branded questions, which is why the subject's own domain is excluded from the source figure rather than shown at the top of it.","term":"Sources and citations"},{"detail":"Company websites were confirmed by opening them, not by taking the domain attached to the name in the data. That mattered: the roster in the source data lists Spectra Aluminum Products against a data broker's domain and MAP Inc. against a mapping software company. Where a head office could not be confirmed on the company's own site, the company is marked as origin not confirmed rather than assigned a country.","term":"Identifying companies"},{"detail":"Each question was run twice, a few minutes apart. That is enough to show run to run instability and not enough to average it away. Where the two runs disagree, the report says so rather than reporting the mean as settled.","term":"Two runs"}],"questionsAsked":["What aluminum extrusion capabilities do top Canadian manufacturers offer","Who can fabricate and finish my aluminum extrusions in one place","What is the typical lead time for custom aluminum extrusions","Why would anodizing improve my aluminum extrusion performance","How do extrusion costs compare across different manufacturers","Can aluminum extrusions replace steel in automotive parts"],"downloads":{"json":"https://thepromptgroup.com/research/aluminum-extruders/ca/data/report.json","csv":"https://thepromptgroup.com/research/aluminum-extruders/ca/data/report.csv"}},"figures":[{"number":1,"id":"fig-mentions","name":"The full ranking","finding":"No company holds more than 22 percent of the mentions, and 83 are named","scope":"43 questions naming no company, 3 engines","caption":"Share of the 256 company mentions across the 43 questions that name no company.","unit":"%","series":["value"],"rows":[{"label":"Dajcor Aluminum","kind":"brand","site":"dajcor.com","value":21.9,"Mentions":"56 of 256","Questions naming it":"22 of 43"},{"label":"Can Art","kind":"brand","site":"canart.com","value":7.4,"Mentions":"19 of 256"},{"label":"Hydro","kind":"brand","site":"hydro.com","value":7,"Mentions":"18 of 256","Legal name":"Norsk Hydro ASA"},{"label":"Apex Aluminum Extrusions","kind":"brand","site":"apexextrusions.ca","value":4.3,"Mentions":"11 of 256"},{"label":"Spectra Aluminum Products","kind":"brand","site":"spectraaluminum.com","value":2.3,"Mentions":"6 of 256"},{"label":"Macfab Manufacturing","kind":"brand","site":"macfab.ca","type":"CNC shop","value":2.3,"Mentions":"6 of 256"},{"label":"APEL Extrusions","kind":"brand","site":"apelextrusions.com","value":2,"Mentions":"5 of 256"},{"label":"Bonnell Aluminum","kind":"brand","site":"bonnellaluminum.com","value":2,"Mentions":"5 of 256"},{"label":"Signature Aluminum Canada","kind":"brand","site":"signaturealum.com","value":1.6,"Mentions":"4 of 256"},{"label":"MAP Inc.","kind":"brand","site":"map-inc.ca","type":"Distributor","value":1.6,"Mentions":"4 of 256"}]},{"number":2,"id":"fig-question-form","name":"By question type","finding":"Asked for a supplier the industry answers.
