Why is my site not #1?

My site is (www) dot pcenclosures-direct (dot) com and I am trying to get #1 spot for the keyword pc enclosures.

Now my only competitor owns 4 sites, that are #1-#4! Optimised for the same keyword. The only thing I can see is that their domain is older than mine. I have more backlinks from relevant sites when I check with yahoo and backlinkwatch.

My site is SEO ok, according to w3optimizer.com/ competitors sites need attention...so why am I #5 in the SERPs (google.co.uk).

My hosting company had an issue in December when I fell from #3 spot to #5 I renewed the domain in November and it appears as though the hosting company forgot for 5 days, until I emailed them and it was sorted within an hour.

What can I do to get #1 spot?

 

continue with the SEO campaign and gradually you will come to the first rank.

 

Search engine rankings are gradually process..keep working on your website, soon it will be on top..

 

Yes, but by doing what? More link building...I have 10 x more than my competitors and I can't understand why I am not #1!

 

yes definitely do link building but not at the pace you are doing

 

The links have been built over 16 months...as I don't want to appear spammy to Google.

 

give it time.. you will be on top. however i believe domain age is one factor in this. Try to blog posts. and social book marking. If you already have more links then your competitor
