• Response from tool creator:

A1 Website Analyzer is a Windows and Mac website and link analysis tool.
After a site crawl, it can filter and show you all pages (including broken links
to internal and external URLs), file sizes, response codes, duplicate content,
titles, descriptions, H1, H2 canonical, internal anchor text to pages, link
line numbers, link follow/nofollow states, navigation click length, all top
keywords and a ton of other data. It will also calculate internal link juice
“score” of all pages. (The tool has been in constant development since 2006.)

If configured so, it can also validate HTML/CSS, spell check and
perform custom search for text/patterns throughout entire website
and integrate with various online tools.

There is no fixed limit of URLs (or links for that matter), and the
practical limit is well above 100,000 unique URLs – infact some have
reported success crawling many-million-page websites, but it depends
on factors such as the computer, website and program configuration.

For those with complex websites, the tool features an extensive
set of website crawl “limit to” and “exclude” filtering options.
It is also possible to add multiple “start crawl from” paths.

The program is shareware with a fully functional 30 days free
trial, but if you need a licensed review copy with no strings attached
before testing/deciding, I will be happy to send one of course.

The license is not subscription based and not per-month or per-year.
For those who buy, it is a one-time price at $69 for version 7.x
including a free 8.x upgrade if released within one year of purchase
with no built-in restraints on how long you can keep using the software.

P.S:
It is worth noting that A1 Website Analyzer also has five sibling
tools – one of them being A1 Sitemap Generator, which can create
XML sitemaps, video sitemaps, image sitemaps, HTML/CSS sitemap etc.
