This can be done a number of ways—guest blogging, directory submissions, blog comments, etc. The key thing to remember is that any automated or “hacky” link building strategies are likely to be flagged by Google. So instead of finding ways to generate mass quantities of links, focus your efforts on generating more high-quality links. Here are a few ideas to get you started:
It’s something akin to picking stocks. You want to buy undervalued domains, and sell them later on at a higher price. For example, you can pick a domain that is out of favor, but could be related to some future event. So if you decide that the stock market is likely to crash in the future, you can buy a domain that includes the words stock market crash during a rising market, and then sell it in a falling market.
In the past, a traditional keyword strategy involved mapping a single keyword to a single web page. But the modern SEO landscape is a bit more complex—singular keywords matter less and the focus has shifted to keyword clusters. Keep this in mind when you optimize your content and ask yourself, what variations of this target keyword am I forgetting? What topics are commonly associated with my target keyword? And how do each of these keyword clusters relate to one another?
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.
