Change link in search engine results

How do I change the links wording that is coming up in the search engine.

There is a REALLY big typo and no one clicks because of this typo.

I have Wordpress all in one seo, and I have changed the title of the page, but that was a few weeks ago am I doing something wrong?

You need to change the meta description which is found on the Wordpress page you are trying to edit, usually under the SEO plugin settings. This typically overrides the default template you might have with a plugin like Yoast! SEO.

you need to change meta tags.
meta tags are used to provide information about the site.
change these meta tags according to requirement-title meta tags,description meta tags,keywords meta tags.
the meta tags description is used to describe your website in a couple of sentences,a snippet..so finally you need to change for better result
