      Kerry Jamison's Review Sourced from Google

      It was a pleasure working with Robert Long on a complete revamp of our company website. Our business has used his services for decades but it was the first experience for me. Robert had the creative vision and technical expertise to make the website do everything we needed it to do for an easy-to-navigate, intuitive, user-friendly experience, all while keeping the look and feel of the brand. The final product is more than I ever imagined, providing both helpful information and a strong marketing tool. Robert was an excellent project manager and true professional, building a framework from the start, checking in throughout the process with updates, and able to flex in different aspects as our business offerings evolved. I wouldn't hesitate to recommend Seller's Bay to anyone looking to build or remodel their website.

      Robert with Sellers Bay is all over it. I hired him to build us a new website and manage our Google face to the public. I had a meeting with him prior to start and he was all over it after that meeting. Started almost immediately and got us built up fast. Now we are getting calls based on the Google ads. We have been so pleased with his work we are going to have him move and improve our other website too. I highly recommend Robert with Sellers Bay.

      Highly recommend Sellers Bay, very responsive, upfront about the services that were to be completed for my new website, no surprise charges or anything like that. I dealt with Robert, he was able to make the website look exactly how I wanted it. I am very picky with this type of stuff, and he never had a problem fine tuning everything that I mentioned to him Also, very honest, polite, and easy to work with. Thank You!!!

      I recently worked with the guys at Feverfish on some web content and digital images for my cocktail-making tutorials, and the results were fantastic. They captured the essence of what I wanted to convey. Their attention to detail and ability to deliver high-quality visuals exceeded my expectations. I highly recommend them.

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.

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.
