Renew Domain for multiple years

Do you want to give your website an advantage? You should consider renewing it in advance, this has financial benefits (discounted rates), reduces your admin costs and could potentially have positive ranking benefits. Here is some information we sent to a client before their domain renewal recently to give an idea of the discount available:
Have been monitoring the site and pretty sure everything is in place ready for Google to get its act in order and start improving your sites rank, the links that have been placed pointing to your site will be picked up naturally and have a positive effect on ranking as time goes on. We continue to tweak / update / improve the SEO as per our agreement.
I have had a good idea to improve the site that you may be interested in, every year you have to renew hosting and you can renew for longer than one year in advance which could indicate to Google that the company is ‘more important / serious’ than the competition.
We have renewed our main domain in advance and this has been recommended to a few other clients who have now got us to renew their domains more than one year in advance and this has possibly positively affected those domains. One is renewed 9 years in advance and getting improved visitor numbers since that has been done. Therefore your domain is due to renew shortly, do you want to renew it multiple years in advance? The cost will be reduced also to reflect the advance payment / less admin requirements, using our current hosting fees of £45 per year we are happy to offer you these discounted ‘advance renewal’ options
1 Year  £45
2 Years £80
3 Years £120
5 years £165
7 Years £210
10 years £300
