Earlier, a Google My Business post had a word limit of 100-300. Now, they have changed it to 1500 characters. Although it’s not a revolutionary change, because 1500 charterers roughly translate to 294-320 words, it still provides more convenience over the word limit. How?

Are there any changes in how many characters will Google display on Mobile devices without having to click “learn more”? According to our test, it has increased from 55 characters to 140 characters.

Overall, now you can be able to convince your customers more effectively via Google My Business posts.
