What are SEO agencies?

SEO agencies in the USA are important for helping brands succeed online. They specialize in making sure a brand is easily found on search engines, like Google, by optimizing websites to appear higher in search results.

These agencies are composed of seasoned professionals well-versed in the intricacies of search algorithms, keyword analysis, content optimization, and other essential elements that contribute to a robust online presence. Their expertise extends beyond mere visibility, encompassing user experience, website performance, and the overall effectiveness of online marketing strategies.

SEO agencies can cater to a diverse clientele, ranging from small businesses to large enterprises across various industries. Their services often include website audits, keyword research, on-page and off-page optimization, content creation, and analytics-driven insights. 

Embarque successfully collaborated with a downloadable software program seeking assistance in revitalizing website traffic. Despite experiencing significant growth in 2021, the client faced a decline in traffic over time.

Problem: Free-falling SEO Traffic

The client, a software program, relied heavily on Google and other search engines for customer discovery. However, after a peak in organic searches in early 2021, the traffic steadily declined, reaching a mere 4,406 search clicks by February 16th, 2022. Identified issues included sub-par content, off-topic focus, non-commercial traffic, poor link quality, and an absence of internal linking.

Solution: Producing high-quality SEO content and new SEO content strategy

Two of Embarque’s approaches addressed multiple aspects:

Result: Recovery of 50% of peak traffic after half a year & 6x improvement in referring domains

Our efforts yielded significant results. Within six months, organic traffic rebounded from 5,000 to 20,000-25,000 monthly searches. Moreover, the referring domains increased sixfold, soaring from 367 in February 2021 to 1,789 by January 2023. The case study showcases Embarque's proficiency in not only restoring lost traffic but also in substantially enhancing the client's online presence.

Benefits of hiring SEO agencies in the USA

Getting help from SEO agencies in the USA can boost your business in the online world. Here are some of the highlights that these agencies can bring to the table:

Strategic expertise

SEO agencies bring specialized knowledge and strategic expertise, ensuring your online presence aligns with the latest search engine algorithms. From keyword optimization to content strategy, their proficiency maximizes your visibility in search results.

For example, we helped Upscribe achieve a fourfold increase in organic traffic within five months by implementing a tailored SEO strategy, revitalizing their online presence and user engagement.

When Upscribe approached us for assistance, they were facing sluggish growth in website traffic. Despite positive reviews from their existing subscribers, attracting new users proved to be a challenge. With organic traffic plateauing at 400-500 between 2021 and 2022, Upscribe needed a turnaround.

Embarque devised a tailored SEO strategy entirely from scratch. This involved identifying suitable topics, researching high-performing keywords, defining the target audience, conducting competitor analysis, and crafting a comprehensive link-building plan.

Upscribe witnessed a significant rise from the initial 400-500 monthly organic searches to hitting a milestone of 700 organic searches in October 2022.

Cost-effective solutions

Hiring an SEO agency is a cost-effective investment. Instead of allocating significant resources to in-house SEO efforts, outsourcing to professionals allows you to benefit from their experience without the overhead costs associated with maintaining an internal team.  

Customized approaches for diverse needs

SEO agencies tailor their strategies to meet the unique needs of your business. Whether you're a startup aiming for local visibility or an established brand targeting a national audience, their customized approaches ensure effective and relevant optimization.

We provided a customized solution for one of our long-time clients, UXCam, addressing their challenges with low-quality SEO content. In just 6 months, Embarque achieved remarkable results, nearly doubling UXCam's organic traffic while significantly enhancing user engagement and lead generation.

UXCam faced issues with poorly written content lacking a clear strategy for driving traffic and generating leads. Responding to UXCam's directives, we implemented a strategy targeting commercial, bottom-of-the-funnel queries with high conversion potential. Each article was given a clear "goal," addressing issues UXCam could solve for the reader or showcasing the benefits of their product. 

In January 2023, UXCam's website received approximately 9,333 organic visitors per month. After six to seven months of content optimization by Embarque, the organic traffic surged to over 17,153 visitors per month, predominantly driven by high-conversion, commercial queries.

Continuous monitoring and adaptation

Search engine algorithms are evolving regularly. SEO agencies provide continuous monitoring and adaptation, ensuring your strategies remain effective and up-to-date with the latest industry trends.

Measurable results and analytics

SEO agencies utilize advanced analytics tools to track and measure the success of their strategies. From keyword rankings to website traffic, these measurable results provide valuable insights, enabling data-driven decisions for ongoing optimization efforts.

Criteria to consider when choosing an SEO agency in the USA

When checking out the best SEO agency for your business, consider the following factors:

Services offered

Ensure the agency provides a comprehensive range of SEO services, including on-page optimization, content creation, link building, and analytics. A well-rounded service offering ensures all aspects of your online presence are addressed.

Proven track record

Embarque proudly showcases a proven track record through an array of comprehensive case studies. These real-world examples highlight our successful collaborations with diverse clients, illustrating the tangible results achieved in areas such as organic traffic growth, enhanced user engagement, and improved lead generation.

For instance, we helped MetorCruise increase their search traffic to more than 2 million visits per year, have a year-on-year growth rate of 1,600% over the three years they worked with us, and monthly trials by 1,000% in the past 18 months.

Client testimonials and reviews

Look for client testimonials and reviews to gauge the satisfaction of previous clients. Positive feedback is a strong indicator of the agency's reliability and customer-focused approach.

Embarque has garnered praise and recognition from our clients through heartfelt testimonials and positive reviews, underscoring the impactful results of our services. Our clients consistently express their satisfaction with Embarque's ability to tailor strategies to their unique needs, fostering increased organic traffic, improved user engagement, and successful lead generation. 


Selecting an SEO agency that prioritizes transparency is crucial for establishing a strong and collaborative partnership. Transparent communication not only builds trust but also ensures that you have a clear understanding of the strategies and practices employed throughout your campaign.

Customization and flexibility

The intricacies of SEO demand a tailored approach that recognizes the individuality of each business. Opting for an SEO agency capable of customizing strategies according to your specific goals is paramount. This adaptability extends beyond your immediate goals to accommodate the inevitable changes within your business or industry landscape.
