How to get sitewide links like picture

Hello, for a long time, our competitors have been receiving sitewide links from very reputable domains that have visits. Does anyone know where I can buy these sitewide links? I would be very grateful if you could help.

The BHW marketplace has providers selling sitewide links, also known as sidebar links or footer links - check this search: https://www.blackhatworld.com/searc...[nodes][0]=43&c[nodes][1]=206&o=relevance&g=1
Also, you can try sending an enquiry to the sites in that list that interest you, and maybe get a better deal direct from the website owner.
