It's somewhat depending on profession and tier. From my experience, tailor recipes usually sell better (at higher prices) than most other professions, and cook recipes rarely sell at all. Esp. at T7 and T8 it's easier to sell unopened scrolls than identified recipes as the number of different recipes is rather small, and the supply is rather high, so many people will already have all available standard recipes but might buy unopened scrolls in hope to find a new recipe.

For T1-T6, those are usually not worth putting in AH as they have a high item value, so the AH fee is also quite high and the demand is limited. You usually get more money for them from the vendor than from AH, esp. if you include the posting fee.
I have tons of "increases crit chance with journeyman/expert/artisan xxxxxxx craft" do these generally sell well and are worth keeping?
For T7 and T8 the items are more useful, but it depends on current supply/demand on wether it's worth selling.
