GOOGLE OFFICIALLY INCREASED THE SNIPPET LENGTH IN SEARCH RESULTS

Google Officially Increased The Snippet Length In Search Results
Google has said that it has made modifications to the mode it presents snippets in search results. A snippet is the explanation of a page shown below the URL in an organic search result that helps out to explain how it is linked to the search query.

A Google’s representative told that:

We currently made a variation to give more descriptive and useful snippets, to help people better realize how pages are related to their search queries. This resulted in snippets becoming somewhat longer, on average.

Over the Last week or so, many have already noticed that the snippets were longer than what’s typically been revealed.

SEO software RankRanger used for analyzing these as well and based on its tools, the snippet length has increased from 160 characters to approximately 230 characters normally. Here’s the growth graph.

Some webmasters and SEOs may consider updating their Meta descriptions, but I don’t believe Google would propose doing so. The snippets are over and over again dynamically generated according to the user question and content found in both the Meta description and the content noticeable on the page. If Google is going to go away with a longer snippet, it possibly will draw that content from the page.
So how is this going to really change SEO?
It changes how digital marketers should write and optimize the meta description. The digital marketers can write the description little bit different because now they will have more space. But they have to be very careful about what they write and answer the user’s query in the search itself and there is a good chance that Google will rank them higher.

It is possible that the websites with longer Meta descriptions will get more clicks on some more complex queries, because people are more enticed by the longer description.

What should SEOs do?
Make a priority list — you should probably already have this — of your most important landing pages by search traffic, the ones that receive the most organic search traffic on your website. Then re-optimize those Meta descriptions for the longer limits. They’re probably between about 250 and 300, and you can optimize the description for your landing page somewhere in there.

The second thing is if your CMS has set of rules around how long you can make a meta description, you may need to update those from the old limit of 160 to the new 230 -320 range. Somewhere in there is where to want to stay.
