Pingcrawl

Description

Pingcrawl aims to replicate WordPress.com’s “Possibly related posts” capability. It queries Google Blog Search for related blog posts (based on tags, or the post title if there are no tags), tries to verify that they are pingback/trackback compatible sites and, if so, adds links to such posts to the end of each blog post where it is invoked.

Scope-limiting configuration options are included to enable Pingcrawl to fit any WordPress installation’s memory/execution time budget.

Licence

Pingcrawl is free software released under the GPL. If you find it valuable, you’re invited to make a small donation toward its ongoing support and maintenance.

FAQ

Why does it take so long to post articles now?

Pingcrawl needs to fetch and process a lot of web pages in order to do its job. Get patient.

Why do I get a “Page not found” error when posting?

The script is either running out of memory or executing for too long.

This can be remedied in two ways:

  • Reduce the max tags, max pings per tag and/or Google hits options.
  • Increase PHP’s max_execution_time and/or memory_limit in your php.ini.
How can I prevent Pingcrawl from running on a given post?

Two ways:

  • Disable the plugin until you want to use it again.
  • Before publishing the post, create a custom field called ‘pingcrawl_pinged’ and set its value to ‘1’.
How can I re-ping a given post?

Delete the ‘pingcrawl_pinged’ custom field from the post.

Why don’t my pingbacks/trackbacks show up at the sites I’m pinging?
  • Blog owners may delete your ping/trackbacks.
  • Blog owners may mark your ping/trackbacks as spam.
  • If you’ve been spammy with pings in the past, your new pings might be marked as spam by anti-ping-spam plugins.
