Post url not matching with post title ( wordpress)

[toxicpls]

I have this site called searchoflife.com on which I have noticed the post urls are not matching with the post title. For Example:Post Title - A Dialogue With NaturePost URL - http://searchoflife.com/dialogue-nature-2013-09-12 Words like 'A' and 'with' are not present in the post URL. This has been the trend since a few days. After investigating I found out that it was due to my plugin SEO ultimate which is actually creating post slugs automatically for the post urls. So my question is whether it is advisable to use post slugs instead of the full post url. Does it affect the SERPS for my site?

Hello Again,

Last night I searched a few keywords and noticed a post which is ranking on the first place at first position. Now this post is having the post slug instead of the entire URL. Here is the keyword

liberation from innate darkness - 1st position

empathy is the liberation - 5th position

Post Title - Empathy is the liberation from Innate Darkness

Post URL - http://searchoflife.com/empathy-liberation-innate-darkness-2013-09-02

Also I checked on my localhost after disabling the slug optimizer. It seems that wordpress is automatically redirecting to the new URL so it won't be a problem to change the older post slug URLS yo complete URLs. But I feel I won't touch those posts which are already having good rankings with post slugs. Any suggestions?

I haven't thoroughly checked the newer posts as such. Unfortunately when I noticed this change it had already started and I thought it to be an update of Wordpress 3.6. Wordpress it seems has its own post slug since quite sometime. But incidently the update of SEO ultimate plugin too coincided with the wordpress update. So I wasn't sure. Later on another site I noticed the same type of behaviour which was using SEO Yoast plugin. So I don't know why all the top SEO plugins are automatically switching to this. I did search on Google regarding this but haven't found a comprehensive answer.

How are your rankings and more importantly traffic generated by these posts doing? You are right you need to be sure before taking this action and to be honest I think there is a good chance that the difference will be negligible even though I think we both agree that we would prefer the full post title URL. If we strip it back to a very base level then you are getting your most important keywords in the URL which is helping your page relevancy so why make this extra work for yourself.

I too am not that comfortable with the post slugs personally. But now that there are already a decent amount of posts (More than 50) in that format which are indexed on Google. If I do disable the post slug option I would then have to change all my urls to the post title (i.e if it really does hamper SERPS), then will have to redirect all those URLS to the new URLs. So need to be sure enough to take this action.

Also one of my posts with the keyword 'astrobiological approach' when searched on Google ranks first in the search results. But if you notice that particular url is having the entire post title. However I'm not sure whether the URL itself had a role in the ranking. Please guide me. Thanks.

Hi - I tend to always set the urls to be the full post title. You will also notice that the likes of Moz does this as well if you look at this post for instance. Your plugin is trying to be clever as there is thought that having too many hyphens and words in your url will dilute the effectiveness of your main keywords once you start going over 4 or 5 words, depending where the keywords occur in the title. I believe Matt Cutts addressed this in a webmaster video many moons ago and I think the main conclusion was that having too many hyphens in your URL may look a little spammy to searchers and put them off clicking on your result in the SERPs. However nowadays this is a common practice and I don''t think this has negative impact on click through rates from the SERPs. If I were you I would look at my URL matching my post title personally. Small words such as A and with help to add context to your page contents in my opinion.
