MarGen is an AI visibility agency that also builds software. The same thinking that powers our client work in generative engine optimisation gets productised into tools anyone can use, whether they work with us or not.
Two products are live today. More are in development.
SaaS-SEO
A curated directory of backlink opportunities for SaaS companies. Stop trawling spreadsheets and cold lists. SaaS-SEO gives you a vetted, graded directory of guest posts, niche edits, directories and resource pages, then lets you track every placement from shortlist to published.
| What it is | Subscription directory of vetted backlink opportunities |
| Who it is for | SaaS founders and marketers running link building in-house |
| Price | £49/month, one plan, everything included |
| Website | saas-seo.co.uk |
Every opportunity is vetted and graded before it reaches the directory. Free self-submit directories and resource pages sit alongside paid placements, with the host’s price shown up front, so you always know what a link actually costs before you commit.

AI Visibility Score
A free tool that scores any website’s AI citation readiness. Enter a URL and get a score out of 100 across four pillars: crawlability (can AI crawlers reach you), structure (can they extract clean answers), entity trust (do they know who you are) and technical foundations. You also get your top three gaps and what to do about them.
| What it is | Free instant AI-readiness scorer |
| Who it is for | Anyone who wants to know if AI assistants can cite their site |
| Price | Free |

Why we ship software
An agency that only writes recommendations is easy to doubt. An agency that ships working products has to be right in public. Building software keeps our GEO thinking honest: the tools encode exactly what we believe matters for AI-era visibility, and they get tested by real users every day.
Each product also comes from a real, recurring job inside our client work. Links from authoritative sources remain one of the strongest signals both Google and AI answer engines use, which is why our first product tackles link building. The free score tool exists because the first question every prospect asks is “where do we stand?”
