It would be much better for seo if the URL:
http://www.sheltie-forum.de/index.php?u=/topic/153/sheltie-und-der-doppelg-auml-nger/post-330

is linked as:
http://www.sheltie-forum.de/sheltie-und-der-doppelg-auml-nger-153-330

Can you implement that?

Hi,

This can lead to conflicts and so is very difficult to implement.

Hi Adesh,
you just need a .htacccess rewrite rule and change the internal linking.
It would be a great boost for SEO.

Hi,

You can make the urls more SEO friendly by enabling SEF in sites/default/constants.php

define('SEF', 0); //Search engine freindly urls , 1=> enable , 0=> disable

Set it to 1.

You need to edit/create the .htaccess file as given here:
https://codoforum.com/documentation/configuration

Well, it should not be much difficult. You need only slug in categories, topics and posts table. Slug is generated on the basis of title, and check if slug already exists (if so just add "+1" in link.
For example, title is: "how to build website?", slug will be "how-to-build-website" (also you can skip short words (2-3 char length). If this slug already exists, just add +1, like "how-to-build-website-2".

I don't see purpose of links like:

index.php?u=/topic/{TOPIC_ID}/{TOPIC_TITLE/SLUG}

It should be simply:
topic/{TOPIC_ID}/slug/
forum/{FORUM_ID}/slug/

Or make slugs to be unique and remove topic/TOPIC_ID/ in links.

Hi,

It should be simply:
topic/{TOPIC_ID}/slug/
forum/{FORUM_ID}/slug/

But, it is like that currently.
You just have to enable SEF.
