Take Control of Your SEO with the Darkstar Keyword Manager Plugin

Keyword Manager ends the spreadsheet nightmare. You export a massive list from SEMrush, Ahrefs, or Moz. Then another from a different project. Soon, you have 20, 30, or more spreadsheets living on your desktop. You lose track of which keyword belongs to which topic cluster. You cannot tell if you already optimized a page for a specific term. This chaos slows you down and creates duplicate work.

That is exactly why we built the Darkstar Keyword Manager. This SEO plugin was conceived because of the extensive SEO work we do and the problems we faced with all our in-depth keyword research spreadsheets. With ongoing projects, we kept creating more and more keyword lists, and it became genuinely hard to track them all.

So we built a solution. The Keyword Manager allows you to upload and manage every keyword within your WordPress site using one simple, clean interface.

Key Features That Fix Real Workflows

• Import from any tool: Upload CSV or XLSX files from SEMrush, Ahrefs, Moz, or any other platform.
• Smart column mapping: The plugin auto-detects search volume, difficulty, and keyword columns.
• Named lists: Organize keywords by campaign, client, or topic cluster.
• Duplicate detection: Find and delete all duplicate keywords with one click.

Most SEO plugins charge a premium to show you which page targets a keyword. Rank Math hides that data behind a paywall. We decided to include it in our free version. You get direct integration with Yoast, RankMath, SEOPress, and AIOSEO. See exactly which URL on your site is optimised for which keyword without paying a cent.

Free vs. Pro – Only One Keyword Manager Feature Requires Payment

We initially launched a paid Pro version with many sorting and list management features. Recently, we decided to make almost everything free. There is only one exception.

If you have reached the stage in your SEO skills where you need to export your keyword lists (including targeted page URLs), please help us out by purchasing the Pro version. That single feature – CSV export with URL mapping – is the only thing behind the paywall. Everything else is completely free.

We will be adding more features as we get feedback and requests from users, please reach out if you have a feature you would like to see added to the plugin.

Manage Multiple Articles with the Keyword Manager

Managing keyword targeting across dozens of posts requires a centralized system. Here is how the Keyword Manager solves this:

• Upload all your researched terms into named lists (e.g., “Summer Campaign 2025” or “Blog Category A”).
• The plugin automatically detects which published page already targets each keyword using your existing SEO plugin data.
• Filter to see only “unassigned” keywords – terms not yet linked to any page, or filter to see which ones are already assigned.
• Bulk favourite keywords and plan your next content pieces.
• Bulk delete keywords you no longer need.
• Quickly search by any keyword term.
• Sort and filter by search volume, difficulty score, favourites, or keyword term.

No more guessing. No more spreadsheets.
