List Of Free Business Guest Post Niche For SEO Outreach 
Alright guys, me and my team decided to offer a free list of business leads, guest posting links. We work hard to get the best possible results for outreaching and searching leads/website. So, we will start for business niche.
We really love creating content, SEO campaign, structure, techniques. I think it's time to help our clients and readers as well. So there will be 4,500 + website list of business niche that we gathered up. Some will work, some will not. All you need to do is to outreach and do some email outreach, then you can do pitch about guest posting, link placement, link exchange. You don't have to search leads or site owner. You can just blast them with email with your site brand email and do a drip feed of sending email or you can manually send it couple times per day as you wish. It's purely white hat strategy and will take time to outreach, you need to reply about their needs like how many words, types of title, how many do-follow links, etc. And time goes by you will know all the in's and out about guest posting outreach.
How to determine if the site is valuable for guest posting or not?
1.) You need to have a tool for site audit and we used Ahrefs, Moz, Semrush and Majestic to audit sites links. You can check DA and PA by Moz, Domain rank and URL rank by Ahrefs, trust flow and citation flow by Majestic. You can check list of auditing seo tools here. We do offer check up too. Just a tips, be sure to get the site with good amount of traffic, decent amount of domain authority and domain rank.
2.) Check if i'ts indexed in google or not. Just type in the google search bar "
Site:www.example.com" if the domain is not indexed, then it's not a good domain.
3.) check social shares - there are lot's of services that offer free check up for social signal checker. Get the domain with 500 + social shares.
