SEO Error

It's better, but you aren't specifying a valid sitemap. See sitemaps.org - Protocol for the correct format.

Not really.

That says allow, allow (lines 2 and 3 mean allow) Google AdSense bot (line one is the AdSense bot) and this is my sitemap (line 4) which doesn't load a proper sitemap, that's an article feed.

What did you think those rules do?

Just delete everything, this will allow complete access to your site to all search engines: that's a good thing.

If you are trying to achieve something specific, like you have a problem with a bot or you don't want parts accessed, what is it?

First your description of what the disallow does is wrong, it stops search engines completely indexing any URL /search/... Disallowing a webpage (means the same as noindex,nofollow) takes it out of the PR flow cycle completely, which means any links you send to a webpage that is disallow will be wasted, the PR will be completely lost.

Look at your home page and:
Count how many links you have in total (rough estimate will be fine)
Count how many links go to webpage starting /search/..

What's the rough percentage of /search/.... because that's the percentage of PR/link benefit you are loosing with your current robots.txt file.!

I didn't count them, but looks like you could have more /search/... links than none /search/... that's a lot of lost link benefit!!!

If 50% of your links go to /search/... you are wasting 50% of your internal PR, All that hard earned PR/link benefit from building backlinks wasted because of one bad robots/txt rule!

As a Blogger user the /search/ pages are your category archives, not actual search results: you are manually setting with posts are found in one of the searches (it's a category archive).

As long as your category archives use an excerpt of the posts (which it does on your site) there are no duplicate content issues to be concerned about.

You are seriously damaging your sites rankings with that robots.txt file.

If you wanted the /search/... pages not indexed, but not take them completely out of the PR flow you would add a noindex,follow robots meta tag only to the webpages with URLs starting /search/... this would stop search engines indexing the categories (if you think it's duplicates content, it's not) and still allow PR to flow through the /search/.. pages to your posts. The noindex still wastes some PR, overall ~15% of the PR you are currently wasting would still be wasted, so this would recover ~85% of what you are loosing right now and have the same impact on not indexing /search/...

Take my advice as someone who knows more about SEO than any of the sites you've taken advice on this, delete your robots.txt file completely (or make it blank) and don't add the noindex,follow robots meta tag. Allow search engines to index it all.

Want to improve your site, reduce the number of /search/... (categories) webpages: if you can't add half a dozen posts to a category, don't create it, delete all single keyword categories, aim for a minimum 2+ keyword categories like "Breast Cancer Research". Remove the monthly archive widget from your site completely, they serve no purpose.
