Hi, Can you advise which tool I can use to check what my sites ranking is for a particular keyword? Paid (with trial) or free. Thanks

You can use SEMRush.com the free version can only check top 10 keywords but in paid version you can see all the keywords that your site ranks.
Google Webmaster Tools is the best. It shows your rank for multiple keywords. But there are several other tools available. Just google for "SERP Checker".
