An SEO company’s portfolio is critically important, representing 40-50% of the evaluation criteria when properly analyzed. Strong portfolios demonstrate proven capabilities while weak ones reveal limitations or dishonesty. Understanding portfolio evaluation helps identify agencies with relevant experience versus those with impressive but irrelevant achievements.
Relevance matters more than size when evaluating portfolios. Five highly relevant case studies outweigh fifty generic examples. Look for clients matching your industry, size, and challenges. A portfolio full of enterprise clients doesn’t help small businesses evaluate fit. Relevant experience predicts success better than total volume.
Depth of case studies reveals genuine expertise versus surface-level involvement. Detailed portfolios explain strategies, challenges, and specific tactics employed. They show progression over time with multiple data points. Vague portfolios with just before/after metrics suggest limited involvement or poor results.
Recency of portfolio examples indicates current capabilities versus past glory. SEO from three years ago differs significantly from today’s requirements. Recent examples from the past 12-18 months demonstrate current expertise. Outdated portfolios suggest agencies haven’t adapted or lack recent successes.
Diversity across industries and business models shows adaptability. While specialization has value, some diversity demonstrates strategic thinking ability. Agencies succeeding only in one narrow niche might struggle with different challenges. Balanced portfolios indicate comprehensive capabilities.
Portfolio evaluation criteria include:
• Specific metrics with timeframes
• Strategy explanations showing thinking
• Challenge descriptions and solutions
• Client attribution with verification ability
• Visual evidence of results
• Sustained success versus temporary wins
Result sustainability visible in portfolios matters significantly. Show me clients from two years ago still ranking well. One-time successes that didn’t persist indicate lucky accidents or unsustainable tactics. Long-term results demonstrate genuine optimization expertise.
Problem-solving examples in portfolios reveal capabilities beyond standard optimization. Recovery from penalties, successful migrations, or technical challenge resolution show advanced skills. Agencies only showing straightforward successes might lack crisis management abilities.
Client testimonials within portfolios add credibility when specific and verifiable. Generic praise means little without details. Testimonials mentioning specific results and named individuals carry weight. Detailed endorsements from verifiable sources strengthen portfolio credibility.
Missing portfolios or confidentiality excuses raise significant concerns. While some NDAs exist, agencies should have some shareable examples. Complete inability to show work suggests either no experience or poor results. Legitimate agencies proudly display achievements.
Portfolio presentation quality indicates professionalism and communication skills. Well-organized, clear portfolios suggest systematic approaches. Sloppy presentation might indicate disorganized operations. How agencies present past work predicts how they’ll handle your account and reporting.
