SERPTool's answer

Indie SEOs, content marketers, affiliate operators, and small SaaS teams who need real SERP-level competitive insight but can't justify the $99–$500/month tiers from the enterprise tools. Practitioners who want to find low-competition keywords by reading the actual SERP weakness, not by trusting a single difficulty number.

9Proxy's answer:

9Proxy's primary audience includes SEO professionals, market researchers, and data analysts who require reliable and anonymous internet access for data scraping, SERP analysis, and market research. It also caters to businesses involved in ad tech, multi-accounting, and price aggregation, providing them with the necessary tools to perform their tasks efficiently and securely.

SERPTool's answer

SERPTool was built by a solo founder who wanted weakness-based keyword analysis with transparent, fair pricing — and AI search visibility data that nobody else was offering. Existing tools either hide their methodology behind generic difficulty scores or lock useful features behind enterprise contracts. SERPTool is the version they wanted to use themselves: every signal explained in the docs, every credit cost shown up front, and the same data quality from a $20 plan as from a $200 one.

9Proxy's answer:

We are a group of professionals identifying a gap in the market for reliable, affordable, and anonymous proxy services. We then leverage our expertise in network technology and security to create a solution that addresses these needs, leading to the establishment of 9Proxy. The company has grown by focusing on customer needs, technological advancements, and quality service.

SERPTool's answer

SERPTool scores keywords by weakness, not just difficulty. For every keyword it pulls the live top-10 SERP and runs 17 ranking-weakness signals across each result — low domain authority, slow page speed, thin content, broken links, outdated tech, UGC-heavy SERPs, and more — then rolls them into an Opportunity Score (0–100). It also tracks AI Mentions: how often each keyword surfaces in Google AI Overviews and ChatGPT, plus the domains being cited as AI sources. Most keyword tools tell you a single difficulty number; SERPTool tells you exactly why a SERP is beatable.

9Proxy's answer:

9Proxy stands out with over 20 million clean residential proxies, ensuring high anonymity and security for users. With competitive pricing starting from just $0.015/IP and $0.68/GB, 9Proxy delivers reliable and cost-effective proxy solutions, making it an attractive choice compared to many competitors on the market.
