I’ve completed the course lessons, but I wasn’t aware it was being retired, so I’ve lost all my progress. …I know there is an updated course…, but I need to get certified for SEO, please… So, can anyone help me with this problem
Hey @AsmaaOsama 
and welcome back, it’s great to see you again on the HubSpot Community! And thanks for reaching out!
The previous SEO certification was retired on June 23, so if the exam wasn’t fully completed and passed before that date, the old certificate unfortunately can’t be issued.
As you mentioned, the best next step is to take the new updated course to earn your SEO certification: AEO Fundamentals.
I checked internally and I see the SEO course indicated as not completed on our side. If you have a screenshot of the SEO course completed before June 23, please share it so that I can investigate and see what we can do.
Thanks,
Bérangère
The same happened to me. I went through the entire course and had to take a break due to family illness. I signed in today to take the course and it was GONE. VERY upset about this because my organization wanted me to complete the certification. The AEO course appears to be about AI which I do not need.
