The import tool allows you to import keywords from meta tags, extract keywords from a URL, projects, from a text file, or by directly copy and pasting.
Up to 500 keywords can be imported at a time. For example, if the limit for your plan is 5,000 keywords per day, you can import 500 keywords, 10 times in any one day.
If you need to clean up and filter your keywords before importing them, the Search and Replace Keyword Manger tool is an advanced Import and Filter tool.
