We are a SEO Services Team based in Barcelona. For our projects we use our own PBN that with a lot of effort we have been building since 2011.
Check this overview of our website in youtube: https://youtu.be/UnEB5o9Bqz4
Or visit our site: linkbuilders.es
We publish 5 articles of your own with one link inside the article that points to the domain you desire. We publish those articles in two Seo-Authority blogs in our PBN, one article - one blog.
Notice that we DO NOT write the article's content; you must provide it to us. The article's content must be related with the affair you are linking on.
Trying to act-like "natural" linkbuilding against Google, WE WILL NOT publish your articles immediately. The default publish rate of this service is 1 article / 2 days. If you want another publish rate, tell us in the document which will contain the articles: at the header of each article set a publish date or at the header of the documents set the publish rate; 1 article / 3 days, 1 article / 1 week, and so on.
Example:
My name is Mr. Marshall and I own a website about cats called kitties.com. I wanna power up my site by giving some authority and I buy this service. I'm gonna write the articles about cats, set the link to my website and set the publish rate in the document. -> That's a correct submit.
Any doubts, don't hesitate to get in touch with us.
