SEO Optimization for Online Real Estate School

Hello. I am looking for a reputable SEO company for my online real estate school. My currant online course is built in: Front-end & back-end: Next.js typescript Database: PostgreSQL The current Next.js codebase does not appear to have the required SEO foundation implemented. There are missing areas such as dynamic metadata, sitemap, robots, structured data/JSON-LD, hreflang strategy, canonical strategy, and SEO fields for CMS/course pages. I am looking for a professional SEO company who can suggest the best way to proceed. My website sells FREC 1 Course. You can google it to see who the big competitors are. You can see both of the websites here 63hours.com and ru.63hours.com One is in English, the other one is for Russian speaking students. The website is not a small brochure website. It is a custom eLearning system. It currently includes: ● student signup, login, verification, password reset, and profile flow ● custom admin panel ● course chapters and sections ● audio lessons ● timestamp-based text highlighting ● chapter quizzes ● practice exam ● end-of-course exam ● pass/fail logic ● 30-day lockout after failure ● student progress tracking ● certificate/payment flow ● PDF certificate download tracking ● email templates and logs ● Google Sheets sync ● Inworld audio/timestamp generation ● separate English and Russian codebases The English codebase is around 27k lines of code, and the Russian codebase is around 31k lines of code. The English app has 47 API route files, 35 app page/layout files, 7,686 audio files, and 7,685 timestamp JSON files. The Russian version has 47 API route files, 36 app page/layout files, 13,518 audio files, and 13,518 timestamp JSON files. It is a full custom learning platform with many connected parts. One of the freelancers offered to first convert the website to Odoo. He wrote: The current platform is built in Next.js / TypeScript / Prisma. Odoo is mainly Python-based with its own ORM, views, controllers, website templates, backend system, and eLearning structure. So the existing Next.js code cannot simply be copied into Odoo. The current Next.js platform will serve as a functional blueprint. I will rebuild the required features inside Odoo using: ● Odoo built-in features where possible ● custom Odoo modules where needed ● custom website/eLearning templates for the student experience ● custom frontend components where the current learning flow requires them. I don't know if this is the right way to go. Trying to make an educated decision.
