SERP improvements after removing capitalisation

Coincidence, or does Google have a preference?

This might be a simple coincidence, but there doesn’t seem to be much written about the virtues of using – or not using – capitalisation.

eg. Best Red Widget Company in London?
vs.
e.g. Best red widget company in London.

On Saturday I slightly modified my titles and meta data to remove unnecessary capitalisation and the following has happened:

Primary keyword: #1 (up from #4)
Secondary keyword: #2 (up from #5)
Tertiary keyword: #1 (up from #3)

I should emphasise that no change was made other than removing unnecessary capitalisation. The fact that three main keywords have all shown major improvement since this change makes me think Google might just have a preference ...

Has anyone experienced anything similar?

Never so far. Even with three example cases, I find it hard to believe removing the capital letters is the true cause of the ranking change. First, because initial caps are the academic standard for titles in English - and if Google has had any one characteristic over the years, it's been an academic slant.

Perhaps you've found a way to improve "freshness", without actually changing a Title or content.

I've found in the past changing Titles and Descriptions tended to make a page "dip" for a while in the SERP's. Changing capitalization may be considered an update, but not actually changing the content, at least from Google's perspective.
