Netpeak Spider is a comprehensive SEO analyzer which will quickly crawl your chosen website, detecting and warning you about 50+ SEO and site optimisation issues.

It takes a little while to get started. You must sign up for an account (no credit card details required), download, install and run Netpeak's launcher, log in to the account you've created, and ask the launcher to download and install Netpeak Spider.

None of that is difficult, though, and once you're up and running the program couldn't be much easier. Type your website address in the Initial URL box, click "Start" and watch Netpeak Spider go to work.

The program lists issues as they're found, ordering them by severity level: PageRank problems, 4xx errors, missing or empty descriptions, dubious redirects, long server response times, duplicate pages/ titles/ descriptions/ content, robots.txt problems, broken images, and many more.

Selecting any of these issues displays details on every affected page. You'll immediately see the URL, HTTP status code, the number of issues and server response times, and scrolling to the left reveals much, much more: content download time, internal PageRank, Robots.txt status, redirects and target URLs, incoming, outgoing, internal and external links, image counts, and loads of page details and stats: h1 value and length, h1 header count, HTML and content size, text/ HTML ratio, URL base tag, X-Robots-tag and others.

Clicking any of these column headers sorts the table by that item, making it easy to find the pages with the longest response times, group together any broken links, and more.

This report isn't just static text. Double-click most items and you'll be able to view individual details - all the images on a page, the internals links to it, etc - and apply filters to help you find specific data.

The default crawler settings worked well for us, but there are plenty of ways to customise them, if necessary. You're able to define the links to follow, the content types to check, the site issues to look for, the crawling speeds (threads, time delays), and more.

Experts will appreciate options like the ability to analyse external links, and directly check an XML sitemap for issues.
