Using Invenio 0.99.x and interested in SEO? You should definetly try to avoid duplicate title‘s! When viewing a record (for instance, http://yourinveniopage.com/record/XXXX), you will notice several tabs on top: Information, Discussion, Usage Statistics…
These links show different content, but the same <title>> Not great for SEO purposes. Use Google’s Webmaster Tools and you will notice this (Diagnose > HTML Suggestions > Duplicate title tags)
There are several ways to avoid duplicate titles. The easiest is to use robots.txt to avoid indexing, or even add a rel=”nofollow” (or even noindex) to the link tabs.
Using nofollow (or noindex) to avoid comments pages from being indexed
You just have to add a rel=”noindex,nofollow” to the html a tag.
Edit $PATH_TO_cds-invenio/lib/python/invenio/webstyle_templates.py
Search this:
elif label != _('Fulltext') and label != _('References') and label != _('Citations'): out_tabs += '<li%(class)s><a href="%(url)s">%(label)s</a></li>' % \ {'class':css_class, 'url':url, 'label':label} |
Change it to:
elif label != _('Fulltext') and label != _('References') and label != _('Citations'): out_tabs += '<li%(class)s><a href="%(url)s" rel="noindex,nofollow">%(label)s</a></li>' % \ {'class':css_class, 'url':url, 'label':label} |
And, as usual, do not forget to run to see changes:
inveniocfg --update-all; /etc/init.d/httpd restart |
Changing the titles of comments pages to avoid duplicate titles
What if we want bots to index these pages? No worries, it can be done by hacking the code a bit.
For instance, lets refer to comments tab. Open /cds-invenio/lib/python/invenio/webcomment_webinterface.py and look for:
title, description, keywords = websearch_templates.tmpl_record_page_header_content(req, self.recid, argd['ln']) |
Lets see how this line works (refer to last line):

How-to fix duplicate title’s in comments

And run this from commandline:
inveniocfg --update-all; /etc/init.d/httpd restart |
