Warning: I spend a certain amount of time each week on search engines, looking for interesting mobile photography sites or posts, and I have
theories about this sort of thing.
The titles of your articles are fairly general, to be relevant to the widest audience. After all, photography is photography, whether it's smartphone, DSLR, or 8x10 view camera, right? But I'm guessing -- only guessing! -- that may be working against you by burying you way down in the search results.
Take the title of that Jo Bradford article I mentioned elsewhere "How to edit your photos with Snapseed." It's more specific, so the actual audience for it is smaller. People searching for "editing photos" aren't likely to see it, but people searching for "editing photos snapseed" are more likely to see it and (I think) more likely to click through to the article AND more likely to react to the article when they see it.
For that same article, if you titled it "Creating custom vignettes with Snapseed," you might be narrowing the search audience too much, but I'm sure that anyone doing such a search would click through to the article.
Everything here should be prefaced with "I think," of course.
