Optimizer
Optimizer is assigned to the SEO category by BotScope. Detection is based on the user-agent string. Current pattern:
\(compatible;\s*Optimizer\)
Optimizer is the on-site crawler of the Sistrix tool — triggered when a Sistrix customer adds a domain to the Sistrix toolset for on-site analysis. UA: Mozilla/5.0 (compatible; Optimizer).
Unlike SeekportBot (Sistrix index crawling, broadly across the web), Optimizer is limited to the specific domains Sistrix customers have configured in the tool. Both bots have been part of the same Sistrix stack since 2020.
SEO tool crawlers build internal databases for tools like Ahrefs, Semrush, Sistrix or Majestic. They have no direct SEO impact — only the tool accesses the data. Crawl frequency grows with your domain authority.
Once Optimizer shows up in your logs, BotScope lets you analyze its crawl paths, status codes, IP distribution and temporal activity — by hour, day or week.
