I'm trying to make a personal web analyzer site using PHP.. I bought a script to get other seo data... Now I want to have the "Unreachable Pages" evaluation like the one shown at the bottom of this page http://free-website-analysis.net/website-analysis/website-analysis-seo-free/... The problem is I don't know how these are computed.. This is not included on the script I bought as well.. I've already googled alot, and I mean a lot, of websites also but I can't seem to find any site like this.. Can anyone help me with the computation or direct me to sites that show this information instead?

  • What is `Unreachable Pages`? – samayo May 24 '13 at 00:06
  • @phpNoOb like "Broken links" maybe.. – Leah May 24 '13 at 00:13
  • The only thing shown as the bottom of that page, is a failure of script, there is nothing said unreachable page, and your should also tag the question with wordpress if your site is wordpress – samayo May 24 '13 at 00:16
  • What? Maybe you're not opening the right page.. There is a table at the bottom of the page.. It's entitled Site Metrics.. I tagged this PHP since that's what I'm using.. Where did you get Wordpress @phpNoOb? – Leah May 24 '13 at 00:27
  • `Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 1 in /home/tratho15/free-website-analysis.net/wp-content/plugins/wassup/wassup.php on line 3954 Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 1 in /home/tratho15/free-website-analysis.net/wp-content/plugins/wassup/wassup.php on line 3954` – samayo May 24 '13 at 00:32
  • That is what I see at the bottom of the website – samayo May 24 '13 at 00:34
  • Oh I see.. You're taking the "bottom" so literally.. Sorry.. The table I'm referring to is just a bit above that error.. :) – Leah May 24 '13 at 00:43
  • Still don't see it. Sorry :) – samayo May 24 '13 at 00:52
  • Well, basically, it's just showing: Unreachable Pages Good – Leah May 24 '13 at 01:00
  • and it is a wordpress site right? – samayo May 24 '13 at 01:04
  • I don't know... All I'm asking is if you know what that means or how to get that evaluation (Good) or if you have other sites similar to that.. – Leah May 24 '13 at 01:10

Here's a list of each item referenced in the statistics, what it means, and where it comes from.

Google Page Rank: This is Google's proprietary calculation. Google does not provide an API to get the Page Rank but there are tools such as this to determine a Page Rank.

Sitemap: The sitemap statistic is simply whether or not the site has a sitemap.xml file. It can be checked by looking for a domain.tld/sitemap.xml file. You can learn about these sitemaps at sitemaps.org.

Robots.txt Much like sitemaps, this just checks for a domain.tld/robots.txt file. This is documented at robotstxt.org

Page Errors: It's hard to tell what page errors are as they could be any number of things.

Unreachable Pages: These are broken links. There are tools like W3C Link Checker that go through all the links on the page and make sure none return a 404 error. You can write a script that turns all the links on the page into an array or object and then use PHP or a command line tool like wget or curl to get the headers of the resource (link). Each time you count a 404 error you increment Unreachable Pages by one.

Domain Age & Domain Expiration: These can be found manually or pragmatically using a Whois search.

Hope this helps and good luck!

EDIT

There is a tutorial on how to write a broken links checker ("unreachable pages") here.

  • Regarding Unreachable Pages, how will I score that total # whether it's good, average, bad?? Is there a calibration for that? – Leah May 24 '13 at 02:42
  • Zero unreachable pages is good. Any more than zero is bad. Unreachable pages should not exist and search engines will always punish you for them. –  May 24 '13 at 03:47
