I wanted to start a thread and find out what everyone's tactics are since the latest update! I will obviously share what I am doing also, we recently acquired a nice domain that is 10+ years old, very keyword specific and has had a website on it for 10 years so has lots of authority in google's eyes however we also have a lesser site that we have had for 1 year and it ranks well locally however we are using the "lesser" site to test out on with low authority links and then the 10+ year old site to only use high authority links.
10+ year old site we have our own high PR blog network that we use and write 300-400 word unique articles and then point a few anchor text links back to the site, this is the only technique we are currently using on this site however very soon I shall be pointing around 100 high PR 4-7 blog comments per week to it.
With the lesser domain we do forum profile links, blog commenting, blog posts but with spun content, directory submissions and so on and to be honest we haven't noticed a drop in the SERP's since the update so I don't know if we have just been very lucky to get away with it as obviously the above techniques are very spammy and low quality.
I was wondering what everyone's techniques are now since the latest G update and if anyone has any recommendations with regards to link building.
