Webmaster is giving errors of Duplicate Meta Descriptions and Duplicate Title Tags after I changes the permalinks structure in wordpress.

It there a quick fix for this and how damaging is the above for seo.

Thanks T

If you have changed the permalinks structure, then I would use a crawler to crawl your own site and look at the meta data. The "duplicate title tags", etc. errors take some time to show up in Google Search Console, at least a day or two. So you may want to re-check it in a few days if you just made corrections on your site.

You can use a campaign here in Moz to check the data, or you can use a crawler like the Screaming Frog SEO spider to check all the data yourself (which is much quicker).

Hi Eric,

I changed the permalinks months ago...

what should I be looking for in Screaming Frog..

Just ran Screaming Frog and it does not show any major duplicate issues..

You'll need to create redirects from the old URLs to the new URLs. Once Moz gets a chance to recrawl this within a month the errors should go away.

If you changed the permalink structure on an established site (not a new site), then it's even more important to create these redirects, both for users and for web crawlers trying to give you credit for your incoming links.

Thanks Kane, Webmaster says that I have 2500 Duplicate title tags and 2300 Duplicate meta descriptions

Is there a quick way to fix these

I am using redirection plugin which redirects the both urls to the same page. Google last crawled the page on the 25th Feb..

The site is 10 years old

Thanks

If you changed 2500 URLs on a 10 year old site and didn't create redirects then you have a much bigger problem on your hands than Moz alerts.

1. Did you create 301 redirects after changing these URLs?
2. Please send an example of a new URL and the old version of that URL.
3. Is your traffic holding steady in Google Analytics since you made these changes?
