Filtering the title tag

It depends on whether or not you’re using an SEO plugin, like Yoast or All-in-One SEO….if so, that would be in the Plugin’s settings.

If not, look in your Theme’s header.php file – there should be a line that creates the <title> tag, check the PHP there and modify it as you like….usually it combines the blog name with the (page or post) title – just remove what looks like your blog name.
