I think for the most part techniques should be avoided, I think people really substitute it for proper analysis. That said, I don't think it should be entirely missing. I mixed it in lightly, so its okay if you feel like "oh no, I am going to have to identify a technique". It doesn't matter so long as you demonstrate a perceptive analysis of language.
Changing grammar around will help. Instead of "the author utilises negative connotations" you can easily say "<language>" connotes <x>
Or even "In saying '"x", the author... <language works in xyz way>"
"Through "<language>"...
Or "<language>" aims to instill ....
"<author> directly targets the younger fact of the audience, "harry potter" appealing to the secondary school students in the forum because xyz"
It's just a matter of writing what you want to say grammatically and showing the language you're about to deconstruct. Again, don't stress too much, if your teacher has been like ''YOU CAN'T SCORE WELL IF YOU DON'T LABEL TECHNIQUES'' - they're full of shit. Doesn't quite matter what you do. My teacher advocated labelling but I disagree. It's the demonstration of your skills that matter.
See I just completely disagree with this. For instance:
"In saying '"x", the author... <language works in xyz way>"
"Through "<language>"...
Or "<language>" aims to instill ...."
All of these come across as assertive to me unless you can ground them in a specific strategy (technique) that the author is using to CREATE those effects. It's not really analysis, because you're not really telling me what it is about those phrases that elicits those effects, you're just saying that those phrases create an effect.
My ideal form for language analysis is:
1. Label a technique
2. Explain the immediate effect of the technique (what is it doing in a vacuum? What is the purpose?)
3. Explain how it positions the audience
eg. "The writer's use of statistics, as in *QUOTE*, grounds the argument in scientific rationality, granting the audience more incentive to perceive the rise of global warming as a valid, realistic threat"
You need all three bits. Only having part 3 will get you to a point, but I think that getting a 10/10 is about making sure you engage with EVERYTHING (and yes, some examiners might be okay if you miss technique labeling, but equally some will immediately dismiss you - you have to cater for all)
