SEO boost for an existing site

Hi fellow blackhatters

I'm looking for an advice on what is the best way to boost a site, a landing page actually. It was doing fairly ok in the past but since no one did any SEO efforts recently it dropped down in SERPS.

I'm doing the redesign of their websites but for now the client wants to know if it is possible to boost the site in any way.

The page in question is this clicky

and the target keyphrase is "24hr emergency plumber"

I'm fairly new to SEO so any advice is appreciated

Analyze backlinks. Analyze keyword density in page. Analyze anchor texts pointing to your website. Discard the low quality backlinks. Build a couple PR 4+ links to your site. Get some nofollow backlinks for link diversity also. You don't need to redesign. You need to find what devalued your site and remove that variable + get quality and "organic" links.

I would suggest to boost your SEO to create amazing infographic and try to offer to "plumber" related sites to embed your infographic by directly contacting them.

Cheers guys. I went through the site content and landing pages in particular and modified keywords and the copy a bit increasing the KW density. Also bought two fiverr gigs to get permanent links to the site from PR5+ domains. Hope it'll work, I'm keeping an eye on the progress in TrafficTravis.

Can anyone suggest a good free tool to track/check backlinks?
