robots.txt file and SEO?

[thegrons]

I currently have the standard robots.txt file that Wordpress includes in their themes. As a result many of my pictures on the website have been indexed by google. If I add a robots.txt file to my site now, will the 404 errors hurt my rankings? Will adding a robots.txt file like the one below help my site in terms of page rank and SERP's?

User-agent: *
Disallow: /wp-content/
Disallow: /wp-content/plugins/
Disallow: /wp-admin/
Disallow: /wp-includes/

Disallow: /cgi-bin/

That robot txt file will more than likely hurt your rankings, you're blocking off a lot of important things which when indexed can help you get traffic, like for example - your images. I don't recommend it. You're also telling it not to index ".php" files --- if i recall, wordpress is a php based engine, you might end up preventing your website from being indexed.

I would stick with the default robots txt.
