Multilingual SEO Enhancement For Travel Website built on PHP Laravel

I run a new travel website built on PHP Laravel. It is live in English and Turkish, and I need to add German and Spanish. My audience is in major cities in India, Turkey, Germany and Spain. This is a 1-month project to build a strong foundation. If the work is good, I will continue with you for the next phase (content and backlinks).

What I need you to do

1. Performance and technical fixes

Raise the performance score on the homepage and all main page types.
Get Core Web Vitals into the green (LCP under 2.5 s, INP under 200 ms, CLS under 0.1).
Check and fix any remaining technical issues (indexing, sitemaps, canonicals, redirects, robots.txt).
Experience with Laravel performance (caching, asset and image optimization) is needed.

2. Keyword research for four markets

Research keywords separately for India (English), Turkey (Turkish), Germany (German) and Spain (Spanish), using real search data.
Deliver a keyword map in the first week: keyword, language, market, search volume, difficulty, intent, and target page.

3. German and Spanish translation, added from the admin panel
Add German and Spanish content for all pages and sections through the website's admin panel.

4. Optimize all four languages (English, Turkish, German, Spanish)
Set up correct hreflang tags, and a sitemap for each language.
SEO: update titles, descriptions, headings, content and internal links for the approved keywords.
AEO (answer engine optimization): add clear, direct answers and FAQ sections on the key pages, so search engines can show them as featured answers.
GEO (generative engine optimization): make the content easy for AI tools (ChatGPT, Perplexity, Google AI Overviews) to understand and cite. This means structured data (Organization, FAQ, Article and others where they fit), consistent company information, and clear author and about details.

5. Backlink groundwork
Full link-building comes in the next phase, but in this month I want:

A list of at least 30 realistic link targets across the four markets (guest post sites, directories, resource pages, PR platforms).
A plan for one link-worthy asset (a free tool, data or a guide).
Only safe methods. No PBNs, bulk packages, classified or bookmarking submissions, or comment and forum spam.

What I expect by the end of the month

performance score above 85+ (before and after screenshots)
Keyword map approved by me
German and Spanish live for all pages, native-reviewed
All four languages optimized, with no hreflang or indexing errors in Search Console
Structured data and FAQ sections added on key pages
Link-target list and asset plan
A final report with what you did and a plan for months 2-4

Reporting
A short update twice a week, and a final report at the end of the month.

Requirements

Proven results on other websites, with links I can check
Multilingual SEO and hreflang experience
A way to get native-speaker review for Turkish, German and Spanish
Experience with AEO and GEO is a plus
Travel or tourism experience is a plus
