Symbol counters placed next to “Title”, “Lead” and “Full Text” fields are to inform you of the number of characters typed. We recommend you not to exceed the stated number of characters.
If your text exceeds the number of characters indicated by counter, that does not mean you have to shorten the text. But it’s better for you to reduce the amount of text simply placing a link to a page that contains detailed information. This will greatly facilitate the work of journalists who do not have time to read all of the text to reveal the value of the story.
It is good for Google snippets as well. Google recommends shorten the title of the press release to 70 characters, and the lead to fit into 150 characters.
