In my previous experiment, I showed that Google no longer limits SERP titles by the number of characters. In the comments on that post, a guy named Marco left a comment that claimed that Google only indexes the first 12 words of a title:
Google indexes 12 words in a Title tag.
For example, if you search intitle:"quanti caratteri google indicizza nel titolo della pagina vero che sono dodici tredici" — 0 results
If you search intitle:"quanti caratteri google indicizza nel titolo della pagina vero che sono dodici" — 2 results
However, I’m not entirely convinced this claim is accurate. Specifically, I’m not convinced that these results are due to a word limit (versus a character limit). So to determine if Google is in fact imposing a 12-word limit, I’ve crafted the title of this post such that it uses short, thin, non-stop-word words.
I’ll publish this and wait for Google to index it…
Ok, the results are in. From what I can tell, it looks like this 12 word limit theory holds up.
Search for this post by the first 12 words of its title: intitle:"trill titi tit tirl tilt till til tiff ti rill rift riff" — it shows up in the search results.
Search for this post by the first 13 words of its title: intitle:"trill titi tit tirl tilt till til tiff ti rill rift riff fritt" — it does NOT show up.
I hate to say it, but it looks like this theory is true. Google only indexes the first 12 words from a page title. (If you can think of some other explanation for the above results, leave a comment.)
