Is it bad that I have about 15 tier 1 sites all linking to the same domain(different landing pages) via different keywords? How long can I continue to link to my site without it looking suspicious? For Example. Let's assume I have a site about ORGANIC FRUITS "best organic fruits" @organicfruits.com "What are the best organic fruits" @organicfruits.com "Healthy Organic Fruits" @organicfruits.com "Best organic apples" @organicfruits.com/organic_apples "What are the best organic apples" @organicfruits.com/best_organic_apples It's only a matter of time until I run out of long tail keywords etc etc. So basically how long do you guys utilize your 2.0 properties for?
