FAQ
Can I use ContentMK without WordPress?
Yes. ContentMK works with any website. Import articles via CSV or sitemap crawl. WordPress sync is optional.
What happens to my data if I cancel?
Your data stays on your machine. The SQLite database is yours. Export is always available, even after cancellation. The app enters read-only mode after a 7-day grace period, but your data is never deleted.
Can I use it on multiple computers?
Your license works on unlimited machines. Without Cloud Sync, each machine has its own database. With Cloud Sync (Professional and Premium), data syncs automatically.
Do I need both SEMrush and Ahrefs modules?
No. Each module is independent. Use whichever SEO tool you subscribe to. Both support CSV import and live API. See integrations.
Is my WordPress password stored securely?
WordPress Application Passwords are encrypted at rest using your OS’s secure credential storage (Electron safeStorage). Stored locally, never transmitted to our servers.
Which WordPress SEO plugins are supported?
Yoast SEO, Rank Math, SEOPress, and All in One SEO (AIOSEO). Detection is automatic during WordPress sync. Manual override available in Site Settings.
Can I use SEMrush and Google Search Console together?
Yes. All premium SEO modules enrich the same data independently. Compare estimated rankings with actual Google positions side by side. Clear source labels show where each data point comes from.
How often does ContentMK update?
Automatically via Electron’s built-in auto-updater. Database migrations run silently with a backup before each one. See the changelog.
Why ContentMK?
vs. Spreadsheets
No health scores, no auto-status, no WordPress sync, no extensibility. ContentMK replaces the spreadsheet you’ve been maintaining.
vs. WordPress Plugins
WordPress plugins only work within WordPress. ContentMK manages content across multiple sites and CMSes. Works offline. Data stays local.
vs. Airtable / Notion
General-purpose tools require manual setup. ContentMK is purpose-built with article statuses, health scores, WordPress sync, and SEO integration out of the box.
vs. SEMrush / Ahrefs
SEO tools focus on keyword data. ContentMK focuses on content management and integrates with both to bring their data into your workflow.
