In the robots.txt disallow the directory http://www.robotstxt.org/

http://www.armstrongsecurity.co.uk/bodyguard-for-hire-london.html is way to over optimized. for bodyguard services etc... also clean up

tags should only be one per page.

On the home page, there is multiple use of the

tag, thats a definite no-no..

I have I similar issue with a client in the travel industry. They got a panda #21 slap, and I am not sure why. They have quality unique content, good visitor/time on page, no advertising, good load times and sensible use of title and h1 tags.

The interesting thing is that the penalty does not seems to be site wide,their blog on the same domain was not affected, and they are still holding position for main keywords.  However for secondary keywords & long tails they are have dropped and in my opinion are being outranked by sites of lesser quality.

I to having been researching possible causes and am at a bit of a loss...

Anybody else have any input?

Don't use nofollow as long as you are happy that the content to not duplicated else where. On the link anchor, I would try and be as informative as possible, so the visitor has some idea of what they will get when they click.

duplicate content is more likely to be affected by Panda updates not penguin updates. Even though you have not experienced any issues todate I would definitely reduce the duplicate content to a min. Otherwise you may be penalized in the next panda update.

I have a client who  wants to run a twitter based competition.

The idea is as follows.

tweet the url of your favorite product from clients website, with #hashtag .

so potentially there could be 100+ tweets  referencing  three or four unique urls on the clients  website.

What I am interested in is there any SEO benefit to be gained from this.

There is <title>which is important both for ranking and is the headline used in the serps and then there is the <meta name="description" title="title that is display below the title in the serps"/> this is not a factor in the ranking algo, but is important as a creative.</p></title>
