    • Step-by-step optimization process with screenshots
    • Common mistakes that cause 75% of resumes to fail
    • How to use Instant Mode for instant optimization

    Step 1: Create Your Free Ajusta Account

    Start by creating your free Ajusta account. You'll instantly receive 1 free optimization - no credit card required. This is enough for 1 complete optimization or 4 ATS score analyses.

    Quick Start Instructions

    1. Visit ajusta.ai
    2. Click "Get Started Free" or "Sign in with Google"
    3. Complete Google authentication
    4. You'll see your 1 free optimization in the dashboard

    Step 2: Upload Your Resume

    Ajusta accepts both PDF and DOCX formats. Your resume design and formatting will be preserved throughout the optimization process - we enhance the content, not the layout.

    Upload Process

    1. Click "Optimize Resume" from your dashboard
    2. Drag and drop your resume or click to browse
    3. Wait 2-3 seconds for AI parsing
    4. Your resume appears in HTML format, ready for optimization

    Cost: 50 credits for upload and parsing

    Step 3: Add the Job Description

    This is where the magic happens. Paste the entire job description - Ajusta's AI analyzes it to understand requirements, keywords, and context.

    Pro Tips for Job Descriptions

    • Copy the entire job posting, including company description
    • Include both required and preferred qualifications
    • Don't edit or summarize - more context = better optimization

    Step 4: Choose Your Optimization Mode

    Ajusta offers two optimization modes. Choose based on your needs and timeline:

    Instant Mode (5 seconds)

    Instant optimization using parallel AI processing. Perfect for time-sensitive applications.

    • • 94% average ATS score
    • • Best for multiple applications
    • • Immediate results

    Review Mode (30-45 seconds)

    Detailed optimization with comprehensive analysis. Maximum accuracy for dream jobs.

    • • 96-98% ATS score potential
    • • More nuanced optimization
    • • Detailed change explanations

    Step 5: Review and Accept Changes

    After optimization, you'll see a side-by-side comparison of changes. Green highlights show additions, red shows removals. Every change is designed to improve your ATS score.

    What Gets Optimized

    Content Enhancements
    • • Keyword density optimization (2.3-3.1%)
    • • Action verb improvements
    • • Quantified achievements
    • • Skills alignment
    Structure Improvements
    • • Section ordering for ATS parsing
    • • Date format standardization
    • • Bullet point optimization
    • • Contact info formatting

    Cost: 100 credits for full optimization

    Step 6: Download Your Optimized Resume

    Once you accept the changes, download your optimized resume. It maintains your original design while incorporating all ATS optimizations.

    Download Options

    • HTML Format: Direct download, preserves all formatting
    • Save as PDF: Use browser's print function (Ctrl/Cmd + P) → Save as PDF
    • Version History: All optimized versions saved in your account

    Common Mistakes to Avoid

    ❌ Using generic job titles

    Always match the exact job title from the posting. "Software Engineer" vs "Software Developer" matters to ATS.

    ❌ Ignoring keyword variations

    Include both acronyms and full terms: "SEO (Search Engine Optimization)" not just "SEO".

    ❌ Over-optimizing

    Keyword stuffing triggers rejection. Ajusta maintains optimal 2.3-3.1% density automatically.

    ❌ Fancy formatting

    Tables, columns, and graphics confuse ATS. Stick to simple, clean layouts.

    Pro Tips for Maximum Success

    🚀 Advanced Strategies

    1. Use the Chrome Extension: Optimize directly from LinkedIn, Indeed, or Glassdoor with one click
    2. Create role-specific versions: Save different optimized versions for similar roles
    3. Track applications: Use Ajusta's built-in tracker to monitor success rates
    4. Optimize early: Submit within 24 hours of posting for 3x higher callback rates
    5. A/B test: Try Instant Mode and Review Modes to see what works best for your industry
