I started a campaign to fish for people with high quality blogs related to my sites. These are good sites that don't typically sell links. I'm paying about $50-100 per post in hopes of getting my sites bumped up from page 2-3 to page one and some sites ranked on #5-10 to #1-5. How many links do you guys usually need from PA-DA sites in the 25-50 range for smaller keywords with 500-1000 searches a month? How long do these links take to kick in? I'm not seeing much movement yet, I noticed these kind of links would work much quicker before. These sites are all high quality with good optimization and several years old that are simply lacking linking power.
