Google shows missing search terms by Karen Blakeman.
From the post:
Several weeks ago I noticed that Google was displaying the terms it had dropped from your search as ‘Missing’. Google started routinely ignoring selected search terms towards the end of 2011 (see http://www.rba.co.uk/wordpress/2011/11/08/dear-google-stop-messing-with-my-search/). Google’s response to the outcry from searchers was to introduce the Verbatim search option. However, there was no way of checking whether all of your terms appeared in a result other than viewing the whole page. Irritating, to say the least, if you found that the top 10 results did not include all of your keywords.
Fast forward to December 2013, and some people started seeing results lists that showed missing keywords as strikethroughs. I saw them for a few days and then, just as I was preparing a blog posting on the feature, they disappeared! I assumed that they were one of Google’s live experiments never to be seen again but it seems they are back. Two people contacted me today to say that they are seeing strikethroughs on missing terms. I ran my test searches again and, yes, I’m seeing them as well.
I ran the original search that prompted my November 2011 article (parrots heron island Caversham UK) and included -site:rba.co.uk in the strategy to exclude my original blog postings. Sure enough, the first two results were missing parrots and had “Missing
parrots” underneath their entry in the list.
At least as of today, try: parrots heron island Caversham UK -site:rba.co.uk
in Google and you will see the same result.
A welcome development, although more transparency would be very welcome.
A non-transparent search process isn’t searching. It’s guessing.
