Marketing tools tend to cluster around SEO + analytics + content. The big platforms (Ahrefs, Semrush, ConvertKit, HubSpot) are real value but cost $99-500+/mo. These twelve free tools cover the daily mechanical jobs — building UTM links, previewing SERP snippets, scoring headlines, generating schema — without the subscription.

The full list

  1. 01 · UTM Builder

    UTM Builder

    Build tracked links for every campaign. Most marketers eventually realize Google's old Campaign Builder is unmaintained — this is the replacement.

  2. 02 · URL Cleaner

    URL Cleaner

    Strip tracking parameters (utm_*, fbclid, gclid) from a URL before sharing publicly. Saves looking like a spammer when you forward a link.

  3. 03 · Headline Analyzer

    Headline Analyzer

    Score a headline on word balance, emotional words, length. Calibrated against the patterns of high-CTR headlines.

  4. 04 · Blog Title Generator

    Blog Title Generator

    Generate 30+ blog title variations from a keyword. Useful for content briefs and editorial calendars.

  5. 05 · SERP Snippet Preview

    SERP Snippet Preview

    Preview how a page will render in Google's search results — title + description + URL — at exact pixel widths. Catches truncation.

  6. 06 · Schema Markup Generator

    Schema Markup Generator

    Generate JSON-LD for Article, FAQ, HowTo, Product, Recipe, Event — the schema types that trigger rich snippets.

  7. 07 · Open Graph Generator

    Open Graph Generator

    Preview how a page renders as an OG card on Twitter / LinkedIn / Slack. Critical before any newsletter or campaign launch.

  8. 08 · Meta Tag Generator

    Meta Tag Generator

    Generate the full meta-tag set (title, description, OG, Twitter, canonical) from a single form. Drop into any HTML site.

  9. 09 · Robots.txt Generator

    Robots.txt Generator

    Generate a robots.txt with the right Allow/Disallow rules and sitemap reference. Trickier than people think — easy to accidentally deindex with one wrong line.

  10. 10 · XML Sitemap Generator

    XML Sitemap Generator

    Build an XML sitemap from a URL list. Useful for static sites without CMS-generated sitemaps.

  11. 11 · Keyword Density Checker

    Keyword Density Checker

    Show keyword density for any text. Most modern SEO ignores density, but it still surfaces over-optimization that triggers spam filters.

  12. 12 · Readability Score Checker

    Readability Score Checker

    Score copy on Flesch-Kincaid grade level. Target 6-8 for marketing copy; lower is more accessible.

Tools this list excludes (and why)

Backlink checkers, rank trackers, audit tools. All require ongoing data ingestion that's expensive to run — the free 'try-our-tool' versions show 1-3 results before paywalling. Better to budget for one paid tool (Ahrefs, Semrush, or Mangools $30-300/mo) than to chase 'free' tools that gate the actual data.

The marketing-tool stack that actually works

For small teams: one paid SEO platform (Ahrefs / Semrush at $129+/mo OR Mangools at $30/mo for budget), one paid email tool (ConvertKit / Buttondown / Beehiiv $20-50/mo), one analytics (Plausible / Fathom $9-19/mo OR free GA4), and the free tools above for the daily mechanical work. Skip enterprise-tier tools (HubSpot Marketing, Marketo) until you have a paid sales team to justify them.
