Is it my back link profile that is affecting my rankings ?

[funktiongolf]

my website www.funktiongolf.co.uk had been ranking well until January and i'm nearly sure its due to low quality links and poor back-link profile i.e over-optimized money keywords

can someone guide me?

thanks for anyone that replies. I really do appreciate the
 help.

Do you have Google Webmaster Tools installed? Generally you will receive a warning from Google before your site is penalized, unless you are talking about just specific keywords. If you can pinpoint the exact dates of the drops, you should be able to see if they coincide with Penguin updates or not.

I think you're right - your link profile is definitely not up to where you'd like to see it.

The thing is, you own control of almost all your links. They are directory submissions, minisites, etc.  You aren't getting a lot of natural links, social linking or anyone talking about you.  You need to generate that "word of mouse" that will get links to you that are out of your control.

Your rankings may have dropped because of the Panda update in January.

Did you start to lose traffic around the 17th January?

The Panda update is based on page content so your backlinks may not be the problem.

What I'm seeing is the overwhelming primacy of relevance. I've seen sites with links from a mere 10-12 websites get top 4/5 positions (beating sites with 50 times as many links) -- because those few links are deemed highly relevant.

A key metric appears (from what I've seen) the referring sites/pages having part or all of the referring keyword (or a variation of it) in their url.
