Analyse Page Titles & Meta Data
Analyse page titles and meta descriptions during a crawl and identify those that are too long, short, missing, or duplicated across your site.
Discover Duplicate Content
Discover exact duplicate URLs with an md5 algorithmic check, partially duplicated elements such as page titles, descriptions or headings and find low content pages.
Extract Data with XPath
Collect any data from the HTML of a web page using CSS Path, XPath or regex. This might include social meta tags, additional headings, prices, SKUs or more!
Review Robots & Directives
View URLs blocked by robots.txt, meta robots or X-Robots-Tag directives such as ‘noindex’ or ‘nofollow’, as well as canonicals and rel=“next” and rel=“prev”.
Generate XML Sitemaps
Quickly create XML Sitemaps and Image XML Sitemaps, with advanced configuration over URLs to include, last modified, priority and change frequency.
Integrate with Google Analytics
Connect to the Google Analytics API and fetch user data, such as sessions or bounce rate and conversions, goals, transactions and revenue for landing pages against the crawl.
