Overview
Sitebulb
Sitebulb is a desktop-based website auditing tool designed to give you a deep understanding of your site's technical SEO health. Instead of just giving you raw data, it processes information to provide prioritized hints and clear visualizations. You can crawl websites of any size and instantly see where your most critical issues lie, from broken links and redirect chains to complex JavaScript rendering problems.
The software helps you bridge the gap between data collection and strategy by explaining why specific issues matter and how you can fix them. Whether you are managing a single blog or a massive enterprise e-commerce site, you can generate professional, branded reports to share with clients or stakeholders. It simplifies the technical audit process so you can spend less time digging through spreadsheets and more time implementing high-impact SEO changes.
Surfer
Surfer is a content intelligence platform designed to take the guesswork out of search engine optimization. Instead of wondering which keywords to include or how long your posts should be, you get a data-backed roadmap based on what is currently ranking. You can analyze top-performing pages in real-time to understand the exact structure, word count, and NLP terms required to compete for the top spot on Google.
The platform serves content creators, SEO agencies, and marketing teams who need to scale their output without sacrificing quality. You can manage the entire content lifecycle from initial keyword research and topical clustering to final editing and auditing of existing pages. It simplifies complex SEO data into an easy-to-follow Content Score, allowing you to optimize your writing as you type.
