Google has made a significant change to its organic search results pages by extending the length of titles and meta descriptions.
Here are the Changes
Title tags have been increased from 50-60 characters to 70–71 characters. That’s at least enough to fit in a few more words.
Meta descriptions have been increased around 100 characters per line, and extended from two to three lines. That’s a very significant increase, and presents far more of an opportunity to tell searchers what the webpage is about.
Some reports show that Google is still truncating the descriptions to two lines for many search results, so you may still see them coming in at around 160 characters at times. When a three line snippet is displayed they come in at 278 characters per line.
