These are PBN (Private Blog Network) links from UK web sites, they are not niche relevant but are very strong and have a strong record of improving rankings and so are very strong and effective links. So you will get a blog post on ten blogs for this service which will include your link, you are free to choose the anchor text for those links and the pages to link to and I can advise on that if you would like so just get in touch. You must have a diverse back link profile in place before ordering links like these so that it looks natural so if you're not sure send me a message and I will check, I have services for diversity link building so can definitely help you build a diverse back link profile if that is needed.
