im tired of link building. im starting to think its a terrible roi. and of course its risky. it wrk but i just wonder : most of us who build quality links also do everything else related to ranking. i wonder if its that 'everything else'thats really responsible for progress in serps. ranking seems to be mainly about domain age, on site seo, number of unique pages indexed, traffic, bounce rate n other user metrics, and of course authority, whatever that is. my question is: has anybody tried to rank by adding 500 wrds new content every sinlge day. doing that, only that and nothing else? how did this affect serps? im doubtful it woud have much affect. just wondering.
