Just in case you hadn’t heard yet, On December 1, 2017, Google (read: Danny Sullivan) officially confirmed that the maximum length of a snippet in their search results has increased to about 320 characters.
How long should my Meta Description be?
Google is now saying that the maximum length for a snippet in search results is 320 characters including spaces & snippet features, like the Published Date. I more often recommend a length of 300 characters for a Meta Description.
However, other data providers like RankRanger have noted that the new descriptions have yet to exceed 300 characters in the wild and are currently averaging out to only about 230 characters.
Do I need to rewrite all my Meta Descriptions for 320 characters?
In a word: No. But while you don’t need to rewrite all your Meta Descriptions this instant, you might want to consider it.
For instance, I’m starting the shift in length with any new pages that Portent or our clients produce. From there, we’ll be working down the list of existing pages starting with high-value pages first.
Most of these longer snippets are being dynamically generated by Google and are highly dependent on the search query. What this means is that it might not matter what you write for the Meta Description if Google thinks they can craft a better one. Thanks Google!
Ultimately we decided to go out and do some light spot checking of our own to see what’s happening out in the wild.
We found out a few interesting things using a super scientific, data-intensive study of two different SERPs, that’s TWENTY blue links people!
- 55% of snippets exceed 160 characters.
- More than half of all snippets are now longer than the old character limit!
- 30% of snippets exceed 300 characters.
- One snippet had two instances of internal truncation. (It looked like the dynamic generator couldn’t make up its mind.)
- 10% of snippets exceed the supposed limit of 320 characters!
Of Meta Descriptions:
- Only 35% of SERP snippets matched the Meta Description for the page! (Which means Google is already re-writing two thirds of the Meta Descriptions.)
- Of the re-written Snippets, 46% were from Descriptions that were longer than 160 characters. (Which means that even if your Description is shorter than the old 160 character limit, more than half of them are being rewritten.)
- Only 1 Meta Description was longer than 300 characters in a targeted attempt to utilize the extra space (I see you Moz) and even THAT ONE was rewritten in the Snippet!
Ultimately, if we want Google to use our expertly written Meta Descriptions, we need to change the way that we write them by using the increased real estate to better answer user questions and encourage click-through. But, even our best efforts may go unrewarded.
How to use Portent’s SERP Preview Tool
If you’re already familiar with our SERP Preview Tool, it’s been updated!
Be sure to clear your cache for this page or do a hard refresh when you get there.
Fun story: I didn’t clear my cache the first time I used the SERP Preview Tool after we updated the character length. Portent’s developer hit me with this gem: http://shouldiblamecaching.com/
