Darkstar Keyword Manager

Description

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)

FAQ

What keyword tools are supported?

Any tool that exports CSV or XLSX: Ahrefs, SEMrush, Moz, Google Keyword Planner, Ubersuggest, KWFinder, Serpstat, and others. The column mapping step handles any column order or naming convention. If you have an ODS file, open it in Google Sheets and download as XLSX first.

Does it work without Yoast, RankMath, SEOPress, or AIOSEO?

Yes. The Targeted Page column simply does not appear if none of the supported SEO plugins is active.

How many keywords can I import?

There is no hard limit. For best performance, keep individual imports under 10,000 keywords and use the per-page setting to manage display speed.

Can I import multiple files?

Yes. Each upload creates a new named list. All keywords are visible in the combined keyword list.

How is Volume stored?

As an integer. Commas are stripped during import (e.g. “1,200” becomes 1200).

How is Difficulty stored?

As an integer 0–100. Values above 100 are clamped to 100.
