Frequently Asked Questions

What should I expect to pay for SEO services in Boston?

SEO pricing in Boston typically ranges from $1,500 to $10,000+ per month, depending on your business size and goals. Small local businesses might pay $1,500-$3,000 monthly for basic local SEO and content optimization. Mid-sized companies usually invest $3,000-$7,000 for comprehensive campaigns including technical SEO, content creation, and link building.

Enterprise-level businesses often spend $10,000+ monthly for aggressive growth strategies and dedicated account teams. Some agencies also offer project-based pricing ($5,000-$25,000) for specific initiatives like website audits or penalty recovery.

How long before I see results from SEO?

Most businesses see initial improvements within 3-6 months, with significant results typically appearing after 6-12 months. Quick wins like fixing technical issues and optimizing existing content can boost traffic within weeks. However, competitive keywords and new content strategies need time to gain traction.

The timeline depends on several factors:

  • Your website's current authority and health
  • Competition level in your industry
  • Budget and resources dedicated to SEO
  • Quality of your existing content
  • How aggressively you implement recommendations

What's the difference between local and national SEO agencies?

Local Boston agencies offer face-to-face meetings and a deeper understanding of the regional market. They know local search patterns, understand area-specific competition, and can leverage local networking opportunities. This makes them ideal for businesses targeting Massachusetts customers or needing hands-on collaboration.

National agencies typically have larger teams, more specialized experts, and broader industry experience. They often provide better value for companies targeting multiple markets or needing enterprise-level resources. However, communication might be limited to video calls and emails.

What services should a good SEO company include?

A comprehensive SEO package should cover technical optimization, content strategy, and authority building. Technical work includes site speed optimization, mobile responsiveness, crawl error fixes, and schema markup implementation. Content services range from keyword research and content calendars to actual writing and optimization.

Essential services to look for:

  • Monthly reporting with clear metrics
  • Competitor analysis and monitoring
  • On-page optimization (titles, meta descriptions, headers)
  • Link building and digital PR
  • Local SEO optimization (if applicable)
  • Regular strategy calls and updates
  • Conversion rate optimization recommendations

How can I tell if an SEO company is legitimate?

Legitimate SEO companies provide clear contracts, realistic timelines, and transparent reporting. They should explain their strategies in terms you understand and never guarantee specific rankings. Check their own website's performance—if they can't rank for their own keywords, that's a red flag.

Warning signs to avoid:

  • Promises of overnight results or guaranteed #1 rankings
  • Unwillingness to share client references or case studies
  • Extremely low prices (under $500/month for full service)
  • Secret or proprietary techniques they won't explain
  • Requiring long-term contracts without trial periods
  • Mass email solicitations or aggressive sales tactics

Should I hire an agency or a freelance SEO consultant?

Agencies provide team-based support with specialized experts for different aspects of SEO. You get continuity if someone leaves, established processes, and typically more resources for large projects. Most agencies require minimum budgets of $2,000-$3,000 monthly.

Freelancers offer personalized attention, flexible pricing, and direct communication with the person doing the work. They're ideal for smaller budgets ($500-$2,000) or specific projects. However, they might lack resources for comprehensive campaigns and could become overwhelmed with multiple clients.

What questions should I ask during an SEO consultation?

Start by asking about their experience with businesses similar to yours and request specific case studies. Understanding their process helps you evaluate if they're a good fit. Ask who will work on your account and how often you'll communicate.

Key questions to ask:

  • Can you share 3 client references in my industry?
  • What tools do you use for keyword research and tracking?
  • How do you measure SEO success?
  • What happens if we need to pause or cancel services?
  • Who owns the content and accounts you create?
  • How do you stay updated with algorithm changes?
  • What's your link building approach?
  • Can I see a sample client report?

What KPIs should my SEO company track and report?

Professional SEO companies track organic traffic growth, keyword rankings, and conversion metrics. Monthly reports should show trends, not just snapshots, and connect SEO efforts to business outcomes. Raw traffic means nothing without context about quality and conversions.

Essential metrics to monitor:

  • Organic traffic by landing page
  • Keyword ranking improvements (especially for target terms)
  • Conversion rate from organic traffic
  • Click-through rates from search results
  • Domain authority and backlink growth
  • Page load speeds and Core Web Vitals
  • Local visibility metrics (for local businesses)

How do I evaluate an SEO company's portfolio and case studies?

Look for detailed case studies showing specific strategies and measurable results over time. Vague statements like "increased traffic" mean nothing without percentages and timeframes. The best case studies include the client's starting point, challenges faced, strategies implemented, and specific outcomes.

Verify their claims using tools like Semrush or Ahrefs to check if showcase clients actually rank well. Ask about client retention rates—good agencies keep clients for years, not months.

What's included in an SEO audit, and is it worth the cost?

A professional SEO audit examines technical issues, content gaps, and competitive positioning. Comprehensive audits (usually $1,500-$5,000) include crawl analysis, backlink profiles, keyword opportunities, and prioritized action plans. They typically take 2-3 weeks and result in a 30-50 page report.

The audit should identify:

  • Technical problems hurting your rankings
  • Content opportunities based on competitor analysis
  • Quick wins you can implement immediately
  • Long-term strategic recommendations
  • Budget and resource requirements for implementation

Free or cheap audits ($99-$500) usually provide automated reports without strategic insights. They're fine for basic issues but won't uncover complex problems or opportunities.

How should I handle SEO contracts and agreements?

Start with a short-term agreement (3-6 months) to test the relationship before committing long-term. Contracts should clearly state deliverables, reporting frequency, and termination terms. Avoid agencies requiring 12+ month commitments upfront without proven results.

Contract must-haves:

  • Specific deliverables and timelines
  • Clear pricing and payment terms
  • Termination clauses (30-60 day notice is standard)
  • Ownership rights for created content
  • Confidentiality agreements
  • Performance benchmarks and reporting schedule

When should I consider switching SEO companies?

Consider switching if you see no improvements after 6 months or if communication consistently falls short. Declining rankings, penalties, or discovering black-hat SEO tactics are immediate red flags. However, don't switch based solely on ranking fluctuations—algorithm updates cause temporary changes.

Signs it's time to switch:

  • No transparent reporting for 2+ months
  • Using outdated or spammy tactics
  • Consistent missed deadlines or promises
  • Significant team turnover affecting your account
  • Refusing to adjust strategy despite poor results
  • Hidden fees or unexpected charges

Before switching, communicate concerns directly and give them 30 days to address issues. Document everything for a smooth transition to a new provider.
