Digital Advertising Review from Jessica Donoghue
Path is an excellent digital agency partner in a multitude of ways. Not only are they a nice group of people to work with, due to their search background all the work they do whether social campaigns, social influencer programs, search, digital advertising, whatever, they are results orientated & data driven. They are methodical and detailed. I trust my money with them. It has been a pleasure working with them.
Digital Marketing Review from Justin J. Hill
In working with Path Interactive for the past few years I have always found their firm to be on the cutting edge of emerging digital marketing trends and always providing valuable insight and planning of our PPC and SEO efforts.
Brand Strategy Review from Eric Spoley
My experiences with PATH have been excellent. They are one of the most responsive agencies I have ever worked with and they are very clear about their insights even if it does not put them in the best of light. Something I cannot say about all the agencies that I have worked with. Projects were always completed inside the budget and on schedule and they always did everything they could to support the brand.

Web Design Review from Christopher Calarco, D.C.
Our company had an excellent experience partnering with Jeremy and the 97 Switch team on our website and SEO. The initial build was on a tight timeline that was kept, and after the sites completion we saw a significant increase in new business coming our way. More medical professionals learned about us and wanted to join our network, which was an amazing bonus of working with 97 Switch. We've committed to work with 97 Switch for the next several years given they have been crucial in guiding our plan for growth.
Web Design Review from Justyna Chrupek
We hired them to build a new website. The website was quickly completed in just a couple months, and weve seen markedly positive results from 97 Switchs efforts. It's a new marketing feature that we use on a daily basis. The improved quality has facilitated our communication and made things much easier. Weve received great feedback from our vendors, investors, and customers who want to view our properties. Internally, our staff is excited to see what's going on in our company. We are definitely proud of our new platform. Our executive team is excited to be featured on the new website; previously, they didn't even want their picture shown. Before this redesign, we were almost embarrassed to send out the link. Now, we can comfortably share it with our investors, potential investors, and landlords so they keep track of our updates on a monthly basis. We love how this site presents the face of our company.
Web Design Review from Adam Greenberg
We've seen tremendous growth and exposure. The website has generated a number of new leads and weve received tons of cold calls from potential clients. This is thanks to 97 Switchs efforts to increase our digital exposure. We communicate primarily via phone and email and theyre highly responsive. I receive a response to emails within minutes and they get back to me within half an hour if I request a phone call. They're able to conduct face-to-face interactions in order to truly understand the goals and business culture of their clients. This allowed them to create a design that accurately represented our brand. I've had nothing but positive experiences with 97 Switch and Id recommend them to anyone.

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:
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:
Outdated SEO practices:
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.
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:
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:
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.
