Google appears to Change Algorithm: Using Capital Letters Creates New Keywords
Keyword research tools may be in for another overhaul.Google’s algorithm now appears to be viewing the capitalized versions of keywords as separate from the lowercase versions.I came across this while searching for the lowercase and uppercase versions of the keyword “engagement rings.”Look at these screen shots from the 188.8.131.52 datacenter.

Searching with a capital “E” gives different results than searching with all lowercase letters, and I also noticed discrepancies between lowercase and uppercase letters with that keyword at the 184.108.40.206 datacenter.
Now, look at the differences in the SERPS at the 220.127.116.11 datacenter for the lower and uppercase version of the keyword “dog tags.”The results change after the second search result.

Assuming this isn’t a temporary glitch, the SEO landscape will undergo another transformation.If this reflects a real change in the algorithm, keyword research tools such as Wordtracker and Keyword Discovery will have to be adjusted to compensate.They currently don’t differentiate between searches with lowercase and capital letters.Since the Google search results were believed to be identical for each, they had no reason to.
We’ll have to wait for an official word from Google (if they give one), but right now this is looking at lot less like a glitch and a lot more like a real shift in the algorithm. And it would be a significant one.I would guess that people search with different forms of capitalization as often as they misspell words or use theplural form of words.But it’s just a guess, as there is no keyword research data to back that assumption up….yet.
We’ll have to keep our eyes on this one.
