Hey Ashok! Good question. I work with clients in a lot of different industries, so the tactics I employ are often quite different depending on the client. In general though, creating killer resources around popular topics, or tools related to client services. This provides a ton of outreach opportunity. For example: We had a client build a tool that allowed webmasters to quickly run SSL scans on their sites and identofy non-secure resources. We reached out to people writing about SSLs, Https migration etc and pitched it as a value-add. We built ~50 links to that tool in 45 days. Not a massive total, but they were pretty much all DR 40+.
Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
