(https://ultomiris.com) 📸 Data Snapshot: May 24, 2026Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
There is virtually zero semantic drift between pages. The homepage acts as a gateway to four specific indications (NMOSD, gMG, aHUS, PNH), and the sub-pages deliver deep clinical data for exactly those conditions. The primary signal of ‘long-acting treatment’ is consistently backed by the 8-week dosing interval mentioned across all sub-pages.
Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.

ULTOMIRIS is a medicine that affects your immune system and may lower the ability of your immune system to fight infections.

If you have not completed your meningococcal vaccines and ULTOMIRIS must be started right away, you should receive the required vaccine(s) as soon as possible. 3. If you have not been vaccinated and ULTOMIRIS must be started right away, you should also receive antibiotics for as long as your healthcare provider tells you. 4. If you had a meningococcal vaccine in the past, you might need additional vaccines before starting ULTOMIRIS. Your healthcare provider will decide if you need additional meningococcal vaccines. 5.
