There is one important thing to keep in mind while trying to get more backlinks and that is you want backlinks from other authoritative sites that are related to your site, not just measly little links from off topic non important sites. The more authoritative the site is that you are getting the backlink from the more impact it will have on the quality of your backlink. Also try to look for sites related to your niche or topic, this is important because Google does not like sites that are linking to each other that are totally unrelated. For example, you have a site selling fishing equipment and you have a backlink from a site that is selling gardening kits. It would be better to get links from other fishing sites or possible even some sport sites since fishing is a sport, but do not get links from sites that are totally unrelated, this can actually hurt your PR.
Pay per click advertising offers a couple of distinct advantages over traditional marketing methods. First of all, due to the nature of pay per click advertising, you can be sure that everyone who ends up on your website due to your ads is actually very interested in your product or service. While most would-be customers find banner and popup ads to be annoying or intrusive, they tend to feel very differently about the links that come up via pay per click advertising. That's because the ads are targeted to the search queries they have just entered and are therefore directly relevant to the product or service they are looking for. If a customer reaches your website from one of your pay per click advertising links, you can be sure that he or she actively sought out your site and didn't come upon it by accident. As a result, you'll get more customers who are ready to buy.
