Search engines attempt to rank results for a given search based on their relevance to the topic, and the quality and reliability a site is judged to have. Google, the world’s most popular search engine, uses an ever-evolving algorithm that aims to evaluate sites in the way that a human reader would. This means that a key part of SEO involves ensuring that the website is a unique and relevant resource for readers.
Thanks for bringing up this point - I agree Eric - competitive positioning can help you determine value that you bring to the table that your competitors dont.  I'm all for it.  Neilsen does some reports that provide awareness, likelihood to recommend, sentiment and other insightsfor your site/brand and your competitors. You can also pull some of that type of insight out of social listening platforms like NetBase, SM2, Radian6, Dow Jones, Nielsen, and so many others.  I've even done some hacked compeitove sentiment comprisons before using Search: searching for [brand or feature] + "like", "love", hate", "wish" etc. 

Spider-driven search engines such as Google®, Yahoo!® and MSN® use "robots" or "crawlers" to score websites across the Internet. Robots "spider/crawl" each site and "score" pages based on how relevant they are. A website's score or placement within a spider driven search engine is derived from hundreds of variables such as link popularity, density and frequency of keywords in page content, HTML code, site themes and more.

Practicing SEO now for over a decade, I don’t often come across many blog posts on the subject that introduce me to anything new — especially when it comes to link building. However, I must admit, after reading your article here I had to bookmark it to refer back to it in the future, as I’m sure it will come in handy when doing SEO for my websites later on down the road.

Thanks Jure. That actually makes sense. Exactly: I’ve tested lowering the number of tips in a few posts and it’s helped CTR/organic traffic. One thing to keep in mind is that the number can also be: the year, time (like how long it will take to find what someone needs), % (like 25% off) etc. It doesn’t have to be the number of tips, classified ads, etc.

Thanks Brian for your article. I am in the healthy living niche. I want to team up with bloggers in my own niche where we can share material it makes sense to me. But I have my own unique message and that is what I have been devoted to! Dah! I see now that my focus should be on what is popular among my peers and add to this. I think I’m finally getting the picture! I am specifically into FOOD MEDICINE perhaps I should start writting about the dangers of a Gluten free diet! Not for everyone!
