      Web Design Review from Chris Palliser

      I work with Shift (Solar & Energy Storage Installer) and I had a great experience working with Major Tom on our brand refresh and new website. Their team is knowledgable, thoughtful, supportive, and I feel they personally and genuinely want us to succeed as a business. Shout out to Nathalie! They made me feel like a priority during any request, and delivered a polished functional design and UX that feels both national and locally grounded, exactly what we asked for. Communication was strong throughout, and they were quick to find solutions when challenges came up, as they inevitably do. Thank you, Major Tom! Highly Recommend!

      Digital Advertising Review from Tim Thatcher

      I've worked with Major Tom for just over 10 years in varying capacities across their Paid Media and Social Media teams. I've always enjoyed very positive working relationships, and they have offered great value and strategic guidance to media campaigns. They always add valuable insights into the data and make recommendations to improve overall strategy. It's always felt like a strong strategic partnership and they seem to have a positive working culture. Would highly recommend them as a media partner.

      WordPress Website Design Review from Jamie McCalman

      Major Tom is a strong choice for enterprise organizations that need both strategic thinking and technical reliability. They understand the demands of a national insurance brokerage and bring the right expertise to every phase of a project. Their workflow is structured and efficient, with seamless handoffs between design, development, and launch. Anna provides excellent account leadership. She is responsive, organized, and solutions oriented. From maintaining nearly perfect uptime to rapidly addressing security and technical issues, their team is dependable. The new website components they designed have enhanced how we communicate complex insurance information to our clients.

7 Frequently Asked Questions About SEO Services USA

When should you hire large SEO agencies in the US and when specialized firms?

Hire large US SEO agencies when you need multiple capabilities under one roof, such as technical SEO, content development, PR, and paid media. Hire specialized firms when SEO is your main growth channel, and you have defined needs, such as eCommerce optimization. Specialized SEO companies in the USA provide direct access to senior marketers and offer in-depth expertise in a vertical or region. As such, it best suits businesses that rely on organic search as their primary customer acquisition channel. 

Searchbloom breaks down the most common specialized SEO agencies in the USA: 

  • Local and multi-location SEO companies in the US focus on fine-tuning location data, reviews, and optimizing Google Business Profiles.   
  • National SEO agencies prioritize content strategy, internal linking, and link building initiatives.   
  • eCommerce SEO firms manage catalogs, feeds, schema, faceted navigation, and parameterized URLs. 

What should you look for to ensure the agency is not selling outdated SEO services?

Ask about its specific infrastructure for large language models (LLMs) and real human experiences. Agencies that reply with "exact-match keyword density" and standard text-based blogs are using obsolete playbooks that damage your ranking. 

Here is what separates modern SEO services from outdated ones: 

Modern SEO practices: 

  • Topic authority and content depth
  • Earning editorial backlinks
  • Core Web Vitals and technical health
  • AI search visibility (AEO/GEO)
  • Search intent matching

Outdated SEO practices:

  • Thin pages with high keyword density
  • Buying links or using private blog networks (PBNs)
  • Ignoring page experience signals
  • Optimizing for Google only
  • Ranking for high-volume vanity keywords

How do you audit the USA SEO company's strategy to verify its legitimacy?

You should review its white-hat strategies, link-building practices, and account recovery process by requesting live and documented samples of client work from the past 90 days. 

Legitimate companies will be able to provide these items as proof of their expertise instead of relying solely on their proposals or hiding behind the “proprietary methodology” answer.

What should a USA SEO service proposal include?

A USA SEO service proposal should include the following elements:

  • A baseline audit
  • Defined monthly deliverables and KPIs
  • Named team members
  • A reporting model
  • Contract terms

It should also explicitly state what work is out of scope and the specific triggers for additional billing. 

How long should you realistically wait before expecting measurable results?

On average, you can expect initial results within 3-6 months, such as cleaner indexation, stronger crawl signals, and improved long-tail visibility. Within 6-12 months, SEO momentum builds for more sustained results, including movement on priority terms, more qualified traffic, and stronger conversion performance. 

As estimated by Rock Salt Marketing Cooperative, results tend to progress as follows:  

  • Month 1-3: Early ranking and traffic gains  
  • Month 3-6: Increase in qualified leads  
  • Month 6-12: ROI turns positive  
  • After the first year: Exponential growth and stable revenue tied to traditional and AI search 

How much output do SEO services in the USA deliver in a month?

SEO services in the USA deliver 10-15 hours of work per month for basic packages, 15-25 hours for standard work, and 25-60+ hours for more advanced strategies. 

As described by Funnel Boost Media, how the overall output is dispersed depends on the service tiers and the defined SEO strategy:  

  • Basic SEO: 10-15 hours of work per month, covering technical SEO, a light content plan, a site audit, minimal outreach, and baseline SEO reporting.  
  • Standard SEO: 15-25 hours per month, covering ongoing technical SEO, copywriting, recurring SEO audits, and link building outreach.
  • Advanced SEO: 25-60 hours per month, including in-depth audits, extensive content creation (20-30 pages per month), intensified link building, ongoing technical SEO maintenance, and performance monitoring. 

At what point should you fire the USA SEO company versus giving them more time?

Look for another SEO company when the current one has not presented tangible results after 6 months and shows constant behavioral problems.

Give the agency more time if you are in the first 6 months of your engagement, deliverables are completed on schedule, and the agency proactively flags issues and adjusts strategies accordingly.
