Nine channels, three kept and one on probation: the Unit 3 rationale for MT357 tests each against the shop's trade-in goal and argues its five exclusions in full. Searches like "mt 357 unit 3 assignment example", "mt357 unit 3 sample" and "mt357 unit 3 example" land here.
What a finished MT357 Unit 3 channel selection rationale looks like
A five-page paper built around one table. Its rows are nine channels; its columns ask what the channel would be asked to do, whether the Unit 2 audience uses it for selling rather than browsing, what disappears if it is removed, and the verdict. Paid search on selling queries, such as sell Nikon 70-200, is kept because people typing those words have already decided to sell. Email to past buyers is kept because 3,140 list members bought a mirrorless body from the shop in the last two years and probably still hold older lenses. Search-friendly value pages stay as the owned counterpart to paid search. YouTube in-stream sits on probation for one quarter. TikTok, Instagram ads, programmatic display, marketplace promoted listings and creator sponsorship are excluded, each in its own paragraph.
How a MT357 Unit 3 example is structured
Opening the paper, the objective and audience are restated word for word, because every verdict that follows is only as sound as its match to them. A removal test organizes each justification: if cutting a channel would lose quote starts nothing else would produce, it stays; if something else would catch the same people, it goes. Kept channels receive a job and a single measure each, so the channel list doubles as a first draft of the measurement plan. Probation is handled as its own category with an entry cost and an exit rule, which avoids the usual compromise of keeping a doubtful channel indefinitely. Exclusions get as much space as inclusions, and several concede a real strength, such as Instagram's reach among younger photographers, before explaining why that strength does not serve a seller. Platform descriptions are dated September 2026.
One question per channel
What stops if this channel disappears? For paid search on selling queries, most new quote starts from people outside the shop's list would stop. For Instagram ads, nothing would stop that email and search do not already reach.
Search on the words sellers type
Queries like sell Canon 24-70 or trade in DSLR lens show a decision already made. The paper keeps paid search on that vocabulary and excludes broader camera terms, where most searchers are shopping rather than selling.
Past buyers still holding old lenses
Of 21,600 list addresses, 3,140 belong to customers who bought a mirrorless body from the shop within two years. Email reaches them for almost nothing, and the paper argues no rented channel could identify them as precisely.
YouTube, admitted with a kill date
Switchers watch mirrorless reviews before they search to sell, which is the one reason to test in-stream ads. The test is capped for a single quarter and ends if it cannot show quote starts from the regions where it ran.
Five exclusions, argued
TikTok and Instagram ads reach photographers browsing rather than selling; display retargets without intent; marketplace promoted listings sell inventory instead of buying it; creator sponsorships cost more than a quarter of search for one video of uncertain reach.
Where marks go in MT357 Unit 3
An MT357 channel rationale is judged first on whether anything was left out, and a paper that keeps every platform it mentions fails that test on sight. Justifications describing what a channel is, its user counts and formats, earn less than ones stating what the channel must accomplish for this objective. Exclusions without reasons read as oversights. Credit also goes to papers that separate a channel's audience from that audience's behavior on it, since photographers on Instagram are mostly not there to sell lenses. A doubtful channel kept with no test and no end date draws comment. Platform facts presented as permanent weaken otherwise sound work; ad formats and targeting options change, and several instructors expect a date on any description of them.

MT357 Unit 3 questions, answered
How many channels should the rationale keep?
As few as the objective needs, often two to four for a small business. What graders weigh is the reasoning behind the count: every kept channel needs a job no other channel does, and every dropped one needs a reason. A rationale that keeps six or seven channels with a paragraph each usually reads as a list rather than a selection.
Can a channel be kept as a test?
Yes, and instructors tend to credit it when the test has limits: a capped budget, a fixed period and a result that would end it. Label it as a test, separate from the confirmed channels, and state what evidence would move it into the plan or out of it. An open-ended trial reads as indecision rather than caution.
Should I describe each platform's features?
Briefly, and only the features that bear on the objective. Feature descriptions date quickly, since platforms change ad formats, targeting and reporting often, so note the month you checked. Graders care more about why a channel fits the audience's behavior than about how its ad manager works, and a dated claim reads as careful.
