As answered by people managing Codility and BlogSEO.
BlogSEO's answer:
BlogSEO's answer:
BlogSEO was born out of frustration. Its founder, Vincent, was running a startup where SEO was the #1 traffic source. No ads, no social media, just organic traffic compounding month after month.
But as a tech founder, not a copywriter, he was spending hundreds of hours writing blog posts instead of building his product. He tried using ChatGPT to automate content, but it wasn't enough. The writing was only one piece. Keyword research, competitor analysis, internal links, images, and daily publishing consistency were still entirely manual.
The turning point came when Vincent met an SEO agency founder in Paris who revealed his team uses ChatGPT for every article, but charges clients $3,800/month for just 2 blog posts. The real value wasn't the AI writing, it was everything around it: gathering website context, researching keywords, optimizing structure.
At $1,900 per article, that wasn't an option. And no existing tool automated the full workflow end-to-end. So Vincent built BlogSEO, first for himself. The vision: give it a website URL and watch agency-quality SEO articles appear on your blog every day. No keyword research. No prompt engineering. No manual publishing.
Today, BlogSEO delivers 30 articles/month for $97, fully automated from keyword research to CMS publishing. Vincent uses it across all his businesses and hasn't written a blog post manually in months.
BlogSEO's answer:
Startups, e-commerce stores, small businesses, and solo founders who need SEO traffic but can't justify $3,000+/month for an agency or spending hours writing blog posts themselves.
BlogSEO's answer:
Quality without compromise.
While competitors cut costs by using cheaper AI models, BlogSEO invests in the best available technology at every step, even when it means lower margins. Articles are generated using deep thinking models that cost 6-10x more than standard ones, and images are 2K HD+ using a mixture of three state-of-the-art models instead of cheap alternatives prone to hallucinations.
This philosophy pays off: roughly 15% of BlogSEO's user base are people who switched from competitors after seeing the quality difference firsthand. Beyond quality, BlogSEO also stands out on:
Hands-on support. The team walks you through integration and will invest developer time to make sure your setup works perfectly. No "figure it out yourself" approach.
Constant product improvement. New features ship regularly, including built-in keyword research, analytics, and a backlink exchange network that most competitors don't offer.
Full automation. From keyword research to image generation to CMS publishing, nothing requires manual work. One website URL is all it takes to get started.
The best way to see the difference is to compare a BlogSEO article side-by-side with any competitor's output.
BlogSEO's answer:
Most AI writing tools stop at generating text. BlogSEO automates the entire SEO workflow from start to finish: keyword research, competitor analysis, content generation, internal linking, HD image creation, and direct CMS publishing. One website URL in, daily agency-quality articles out.
Three things set it apart:
The result: 30 fully optimized articles per month for $97, replacing agencies that charge $3,000-8,000/month for a fraction of the output.
