Guest blogging is not something new and many providers offer this service, but beware, there are many services that claim they are a guest blogging service but in fact, are not.
Many other services have a blog network that they use for posting your article, where they own all the sites. This can leave a footprint, and for a white hat product like this, that isn’t what you want. We do not use a blog network to post your articles. All the sites we post to are manually contacted and are real sites.
Some services only include links to your site. We also link out to other non-competing authority sites to be as natural as possible.
Beware of cheap guest posting services – you often get what you pay for.
