Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OnCrawl

  • No pricing is published anywhere on the site, so early-stage comparison against Botify or Lumar requires getting quotes from all three before any evaluation can start.
  • Log file analysis requires the customer to actually supply raw server logs, which many marketing teams cannot get from their infrastructure team without a separate internal project.
  • It is a smaller company than Botify, so enterprise buyers evaluating vendor stability and roadmap longevity weigh that against the lower likely price.
  • The interface and terminology assume a working knowledge of crawl budget and log analysis concepts, so it is a poor fit for a generalist marketer without technical SEO background.
  • Data retention periods are tied to plan tier, so historical trend analysis beyond the contracted retention window is not available without upgrading before the data would otherwise be purged.

Surfer SEO

  • Entry Discovery plan at $49 per month limits users to a single seat and 120 documents
  • AI prompt tracking is excluded on the Discovery plan and capped at 25 prompts weekly on Standard, 50 daily on Pro
  • Unlimited documents on the Peace of Mind plan are subject to a fair usage policy rather than being truly unlimited

OnCrawl: How much does OnCrawl cost?

It is not published. Pricing is quoted based on crawl volume, log volume and retention period; get a quote before comparing it to Botify or Lumar.

Surfer SEO: What is the difference between Surfer's AI SEO plans?

Discovery includes 120 documents and basic tracking. Standard adds 360 documents and weekly AI prompt tracking. Pro adds daily prompt tracking and multiple brand workspaces. Peace of Mind includes unlimited documents, daily prompt tracking, and a dedicated success manager.

OnCrawl: Is this suitable for a small business site?

Generally not economically; the log analysis capability that justifies the cost only pays off once a site is large enough that Google is not crawling every page anyway.
