Description tag length Optimizing All in One SEO Pack Forum

It's not a built in option, so my guess is that any hack you made would then break with the next update. However, I'll bet All In One will by default go to 185 characters or higher soon…

I also ran into the same issue, there's no option to increase the length via the configuration page. I understand search engines truncate meta descriptions but I realize Facebook sharing takes meta descriptions if no og:description tags are found and 160 characters looks a bit short, Facebook allows up to 300 characters.

To increase the description characters, just open up aioseop.class.php and change line 8:

var $maximum_description_length = 160;

to

var $maximum_description_length = 300;
