Darkstar Keyword Manager

Darkstar Keyword Manager lets you import keyword research files from any tool and manage them directly inside WordPress.

Key Features

• Import from any tool — Upload CSV or XLSX files from Ahrefs, SEMrush, Google Keyword Planner, Moz, Ubersuggest, and more
• Column mapping — After upload, choose which columns map to Keyword, Volume, and Difficulty — no reformatting required
• Smart auto-detection — Common column names (Volume, KD, Keyword Difficulty, etc.) are detected automatically
• Sortable table — Click any column header to sort ascending or descending
• AJAX search — Filter keywords instantly with a live search field
• Pagination — Configurable per-page count (10–500) with smart page number controls
• SEO plugin integration — See which published page targets each keyword. Supports Yoast SEO, RankMath, SEOPress, and All in One SEO (single DB query, no performance hit)
• Favourite keywords — Star any keyword to mark it; filter to view only favourites
• Bulk actions — Select multiple keywords to delete, favourite, or unfavourite in one click
• Duplicate detection — Keywords targeted by more than one page are highlighted and filterable with a “Duplicates only” toggle
• Difficulty badges — Easy / Medium / Hard colour-coded badges (0–30 / 31–60 / 61–100)
• List names — Each import is saved under a named list for organisation
• Secure upload handling — Magic byte validation, MIME checking, size limits, randomised temp filenames, protected temp directory, automatic cleanup

Supported File Formats

• CSV — Comma, tab, or semicolon delimited. Auto-detected.
• XLSX — Excel 2007+ format. Parsed natively via ZipArchive + SimpleXML (no library required).

How It Works

1. Go to Keyword Manager → Import Keywords
2. Enter a list name and upload your file
3. Map the columns: which column is the Keyword? Volume? Difficulty?
4. Click Import Keywords
5. View and manage your keywords at Keyword Manager → All Keywords

SEO Plugin Integration

When Yoast SEO, RankMath, SEOPress, or All in One SEO is active, a Targeted Page(s) column appears in the keyword list. If a keyword is set as the focus keyword on multiple pages, all pages are listed — and the row is highlighted as a duplicate. A Duplicates only filter lets you see all conflicting keywords at a glance. RankMath’s comma-separated multi-keyword fields and AIOSEO’s JSON keyphrase format are fully supported. The lookup uses a single database query regardless of how many keywords are displayed.

Requirements

• PHP ZipArchive extension (required for XLSX — enabled by default on most hosts)
• Yoast SEO, RankMath, SEOPress, or All in One SEO (optional, for the Targeted Page column)
