Organic is what people are looking for; the rest of these simply put things in front of people who may or may not be seeking what you offer. We know that approximately X number of people are looking for Y every day. So if we can get on front of those people, we have a much greater opportunity to create long-term relationships and increase our overall ROI.
Network marketing: Network marketing companies have a great business model (for those who own the company), because they only pay their sales people (a.k.a. “independent business owners”) when they make a sale or recruit another person. They only pay on performance. So to sell a bunch of product, the direct sales company really doesn’t go directly to the consumer through TV or magazine ads or similar methods that could easily cost millions; instead they go indirectly through their sales people and only pay for the word of mouth advertising as a commission on a product sale. It’s really savvy business strategy that’s low-risk and high-reward, if it spreads far and fast enough by emotionally exciting the distributors. Distributors are heavily using social media like Facebook, YouTube, blogging and the like to generate sales and grow their network online.
You control the cost of search engine marketing and pay nothing for your ad to simply appear on the search engine. You are charged only if someone clicks on your ad, and only up to the amount that you agreed to for that click. That’s why SEM is also known as pay per click (PPC), because you only get charged for each click that your ad generates. No click? No charge.
If both page are closely related (lots of topical overlap), I would merge the unique content from the lower ranking article into the top ranking one, then 301 redirect the lower performing article into the top ranking one. This will make the canonical version more relevant, and give it an immediate authority boost. I would also fetch it right away, do some link building, and possibly a little paid promotion to seed some engagement. Update the time stamp.
