What Is Keywordly?

The platform treats SEO as an evolving process where automation, AI insights, and content optimization work together to improve visibility across both Google and emerging AI search engines.
What Is Surfer SEO?
Surfer SEO is a content intelligence platform built to help writers and SEO teams optimize on-page content by benchmarking it against top-ranking pages. Founded in Poland in 2017, Surfer has earned recommendations from industry experts and become the standard reference point for content-scoring workflows. It analyzes hundreds of on-page signals from top SERP results and translates them into a real-time content score that guides writers as they work.
Feature Comparison: Deep Dive
Keyword Research & Clustering
Keywordly pulls keyword ideas from Google, Reddit, Quora, Amazon, and YouTube, then groups them using SERP-based and semantic NLP clustering to prevent cannibalization and build topical authority. Surfer SEO includes unlimited keyword research, but its clustering and multi-source discovery don’t go as deep. Winner: Keywordly — its clustering models and cross-platform keyword sourcing are purpose-built for topical map construction.
Content Editor & Scoring
Keywordly grades content in real time against selected keyword clusters and SERP data, guiding structure and semantic relevance as you write. Surfer’s Content Score is its flagship feature, evaluating over 500 on-page signals against top-ranking competitors, with reviewers citing a documented ranking correlation that few competitors match. Winner: Surfer SEO — its Content Editor is more mature, with years of refinement and a stronger data-backed reputation among SEO professionals.
AI Content Writing
Keywordly’s AI writer generates topical maps, outlines, and full articles guided by keyword clusters, brand voice, and semantic context. Surfer offers Surfer AI as a bundled or add-on feature for generating briefs and articles, though several reviews note it functions as a separate tool with different quality from the core Content Editor. Winner: Tie — both produce SEO-guided drafts, but neither fully replaces human editing for competitive keywords.
AI Search Visibility & GEO
Keywordly includes AI Search Tracking, brand sentiment analysis, and competitor gap features aimed at building presence on platforms like ChatGPT, plus visibility into Reddit and Quora forums. Surfer SEO remains primarily focused on traditional Google ranking signals. Winner: Keywordly — this is the clearest differentiator between the two as AI search adoption grows.
Integrations & Publishing
Keywordly currently supports direct publishing to WordPress and Ghost, with additional CMS integrations planned. Surfer connects directly with Google Docs and WordPress, and its Essential plan is built around that simple two-tool workflow. Winner: Surfer SEO — its Google Docs integration is frequently praised as frictionless for collaborative writing teams.
Ease of Use & Learning Curve
Keywordly is described by reviewers as having an intuitive interface paired with powerful analytics, making complex tasks manageable for non-technical users. Surfer SEO reviewers consistently note that the platform takes time to learn, requiring documentation and video training to avoid frustration. Winner: Keywordly — its more consolidated workflow reduces the number of separate modules a new user has to master.
Customer Support & Reliability
Keywordly’s support has been positively noted by early users, particularly around onboarding and resolving product issues. Surfer offers live human support, Surfer Academy videos, and masterclasses, and G2 reviewers specifically highlight Surfer’s quality of support as a strength.
