blend27 - OK, this can be our "m*c and ch*ese recipes"
example for this discussion, a term which we can monitor for a while.
There is a difference, though, which has prompted me to obscure several vowels... in a way that I'm thinking anybody here should be able to guess... but which Google most likely won't be able to parse, or at least not for purposes of indexing and ranking. I've replaced some vowels by asterisks.
My concern is that this phrase is relatively rare compared to the recipe search we were looking at in 2012, and I don't want our use of it to distort results.
Here's the competition level, with no searches indicated on SEMrush....
- all the words (default) - 2,180,000 results
- quoted search - 45,200 results
- allintitle - 6,320
Regarding the domain clustering you're seeing... for this unquoted search, at the default 10 results per page, I'm not seeing what you and Leosghost are seeing. What I'm seeing is not extremely unusual...
- eBay #1
- Amazon #2, #3, and #4
- images following #4
- Facebook #7 and #8
The next Amazon result doesn't show up until the top of page 3. I should add too that the quality of images I'm seeing aren't all that terrible, and there's even a magnifying window you can move over the image. (The merchandise itself isn't all that inspiring, but that's something else). The pages are all fairly heavily reviewed, and the 4 Amazon pages I looked at are all selling different items from obviously the same manufacturer.
What you and Leosghost are describing, though, was typical of what I saw on some wholesaler type results that appeared on Amazon during the 2012 host authority days, but I should add that using 100 results per page is a clustering mechanism in itself, and greatly distorts what most users are likely to see.
Eventually, at 10 results per page, the pages from a single domain did get pared back to 2 per page, as Google made choices among the surfaced pages (starting, as I mentioned, with the first page, and gradually working back to deeper results).
I am guessing that we may be distorting the results on this particular query just by visiting the pages, but I'm not sure of that. On the query I describe that I've been monitoring, I'm careful not to click through. I'm wanting to see indications of traffic that's not related to me.
Regarding these results, I'm assuming that there's some kind of new algo factor that's needing to be calibrated, and I'm wondering what it is. Another possibility could be that this type of sorting needs to be run periodically on different types of pages.
