Netpeak Spider is a Windows-based SEO analyzer which can quickly detect 50+ common website optimization issues.

The program looks for PageRank issues, 4xx errors, dubious redirects, missing titles and descriptions, missing image ALT attributes, duplicate content, long server response times, non-https pages, and a host of other site problems.

Netpeak Spider is normally a subscription based product costing $117 in year one, but there’s a free and unrestricted 14-day trial available, and occasional one month subscriptions can be yours for $14.

The program is designed for extreme ease of use. Launch it, the “Initial URL” box and large green “Start” button appear, and you’ll understand the basics in just a few seconds.

Netpeak Spider displays your site pages in a central table, along with key details like HTTP status code, the number of issues and server response times.

Scanned pages are listed in a central table. Detected issues appear in the left-hand pane, ordered by severity

A right-hand pane lists any issues the program has found, listing them by severity level, and clicking any item the affected pages.

There are many ways to filter and organise this report. At its simplest, you might click the “Server Response Time” column heading to sort the list by that item, quickly highlighting your slowest pages. But you could also double-click an “Internal Links” count to view the individual pages, filter the results and view details on specific URLs.

Crawler settings are another highlight. The defaults (5 threads, follow internal links only) work well, but you can also scan external links, define the content types to analyze, the errors to look for, set custom crawling rules, specify a user agent, or set important restrictions to limit program scans (maximum crawling depth, redirects, canonical chain length).

Experts will appreciate more advanced options, including the ability to analyze an XML sitemap, correct any issues and send the fixed map straight to the search engines.

It’s a very comprehensive system, but SEO newbies shouldn’t be put off. Even if you’re clueless about Netpeak Spider’s more advanced stats, there’s plenty here that you will recognise (4xx errors, slow load speeds) and the straightforward interface ensures you’ll be using the program right away.

Netpeak Spider is available as a 14-day trial for Windows. Mac and Linux builds are reportedly “coming soon”.
