RGray Reviews & Testimonials

Startup Review from Helen Guzenko
Wezom is an enterprise software development company with more than 275 specialists. We brought RGray in for startup marketing and growth marketing for a FinTech SaaS platform we had built for a client, an early stage startup with a finished product and almost no market presence. RGray started with their startup marketing foundation: market and competitor research, positioning and messaging, and a growth strategy built on three prioritized hypotheses, each with its own funnel and success metrics. They then implemented the channels: SEO, GEO for visibility inside AI search and AI assistants, PR and digital media, and paid user acquisition to test the funnels fast. Analytics and attribution were in place from the start.They also built AI into the daily marketing work: a custom multi agent system using Claude, Grok, Perplexity and Gemini for research, content production and localization, handed over with workflows, prompts and checklists. Two of the three hypotheses proved out, so we elaborated those two and their funnels. CAC started at $31 and fell to $16 by the end of the test campaign, below the industry average. The campaign brought around 2,500 activated users, which boosted revenue and gave us real data for funnel, user and product analysis. The client finished with a working acquisition system and the documentation to run it, not a set of campaigns. Project management was on time and on budget: weekly calls, a shared board with owners and deadlines, monthly reporting against the strategy metrics, same day answers. When our client's roadmap moved, they resequenced the plan in days. Most impressive: they think like product owners, not like a service agency, and they challenged our ICP and pricing assumptions correctly. One improvement: the early reports were denser than we needed, and they added an executive summary once we asked.

Charleston SEO Firm Hiring Guide
Why should I hire an SEO agency near me?
You should hire an SEO agency near you because it can provide valuable local insight, allowing for more precise keyword, competitor, and audience analysis. Its proximity means better access to local media, businesses, and influencers for more effective backlink strategies. A nearby SEO agency can also work more closely with you and your team, thus laying the groundwork for more agile workflows and better team chemistry.
Here are more ways an SEO agency near you can benefit your business:
- Understanding of linguistic nuances
A nearby SEO agency can pinpoint the specific terms used by your local audience. These insights enable it to create a more precise keyword strategy for positioning your business on the first page of popular search queries. - First-hand knowledge of local trends
An SEO partner in the area understands how people search, what influences their decisions, and how local trends evolve. That knowledge allows for more accurate keyword targeting, content positioning, and campaign timing. - Cultural fluency and audience relevance
Being part of the same cultural and demographic group enables a more intuitive grasp of tone, messaging, and language. Familiarity with these aspects enables curating campaigns that are contextually relevant and optimized for search engines. - Regulatory familiarity
Local firms operate within the same legal and commercial environment, which makes them well-versed in region-specific advertising standards, data practices, and competitive pressures. - Shared time zone
Working hours synchronicity is very valuable for ongoing SEO work, where timely updates, content approvals, and data reviews play a critical role. With a domestic SEO agency, you won’t have to worry about time zone alignment or misunderstandings due to differences in language and culture. If anything, the proximity will minimize delays and improve responsiveness. - More personal business relationships
With more chances for in-person meetings, you can more easily build a closer working relationship with the SEO agency. Frequent in-person engagements will foster deeper alignment between your business goals and the SEO tactics used to achieve them.

What should I look for in a Charleston SEO firm?
When researching Charleston SEO firms, you should look for an agency with expertise in local keyword targeting, Google Business Profile optimization, and a portfolio of Charleston-based clients. A few other important attributes to look for when selecting a local agency include:
- Positive experiences
Read the agency’s customer reviews and confirm their authenticity by asking for client references or looking through reputable directories like DesignRush. Charleston SEO firms with a good volume of positive customer reviews are considered trustworthy, experienced, and reliable. - Awards and recognitions
Check the firm’s website for accolades and press mentions from Charleston Business Magazine, Charleston Metro Chamber of Commerce, and South Carolina Business Awards. Such recognitions can give you an insight into the agency’s local prominence and credibility. - Proven track record in your industry
Read through the testimonials, client list, and case studies to check if the agency has worked with companies in your industry. An SEO firm familiar with your niche can craft strategies that more precisely capture your market and engage your audience. - Up-to-date SEO knowledge
To keep their SEO knowledge current, agencies should actively track algorithm changes and adapt strategies. Seek a partner that educates, keeps current with new practices, and follows search trends.
What should I avoid when hiring a Charleston SEO company?
When hiring a Charleston SEO company, keep an eye out for the following red flags that can damage your online rankings, visibility, business reputation, and long-term growth:
- Black hat tactics
Keyword stuffing, link buying, adding hidden text, and using AI to manipulate ranking are some of the black hat techniques to watch out for. These outdated practices, also known as SEO shortcuts, can easily lead to lower ranking and penalties. - Lack of local knowledge
An agency without unique insights into the Charleston community may struggle to deliver the local advantages you are seeking. It could also overlook important linguistic and cultural nuances, which can reduce your strategy’s effectiveness. - Guaranteed results
Be cautious of SEO agencies that promise first-page rankings within days or weeks. Such tactics may lead to long-term issues, ultimately requiring you to pay another agency to resolve them. - High employee turnover
High turnover within an SEO agency can lead to inconsistent strategies and a lack of continuity, which may delay results and affect the service quality. Constantly changing teams can disrupt your progress and lead to unpredictable outcomes. - No analytics or reporting
An agency that forgoes audience and competitor analysis, keyword research, and performance tracking relies on guesswork instead of data and is likely to produce generic and ineffectual strategies.
