The SLWCN site has gone global on the internet shooting it's rankings high but looking at the stats I have noticed a very good piece of marketing.
From new sites that linked to us I have noticed quite a few visits from the site, when looking at their site, they have nothing to do window cleaning on their site. They just add your site onto their page, do a couple of clicks then remove the entry. This then encourages yourself to have a look at their webpage when you look at the stats.
Very clever so if you wanted to get a commercial firm to visit your website add them, click the link, then remove.
There is one downside though, I always google search a link as there are some bad sites that try to get you to visit them. Then when you click on their website you get the dreaded virus.
