How To Change Title and Meta For Domain in WP

I've got SEO by Yoast and make sure all my titles and meta descriptions are good. However, the main domain page ranking in google has my tagline and menu options in the meta description.

I have looked all over trying to find where to edit that but I can't find the option.

Assistance would be appreciated.

You can set the title under your "options", "Blogtitle" in the first subpage.

To set your meta description (and maybe keywords), go do "Design" -> "Editor" and select the "header.php" on the right side. Then search in the code for meta tags like "<meta name="description"...". There you can change everything you need.

Thanks!

Have you heard the name of All in One SEO? just install this plugin.
For changing the title you have to go to settings and there you can see the title.
