The strength of your link profile isn’t solely determined by how many sites link back to you – it can also be affected by your internal linking structure. When creating and publishing content, be sure to keep an eye out for opportunities for internal links. This not only helps with SEO, but also results in a better, more useful experience for the user – the cornerstone of increasing traffic to your website.
Let’s say you wish to block all URLs that have the PDF. extension. If you write in your robots.txt a line that looks like this: User-agent: Googlebot Disallow: /*.pdf$. The sign “$” from the end basically tells bots that only URLs ending in PDF shouldn’t be crawled while any other URL containing “PDF” should be. I know it might sound complicated, yet the moral of this story is that a simple misused symbol can break your marketing strategy along with your organic traffic. Below you can find a list with the correct robotx.txt wildcard matches and, as long as you keep count of it, you should be on the safe side of website’s traffic.
Hey Marcus, thank you so much. Hearing all the compliments make me wish I made a list of 100 traffic sources :) I don't think anyone would publish it though...too much work, lol. I hope everyone will use it and find some fresh traffic for their blogs, most of these sources will work for any blog but some will work better for specific niches. Thanks for sharing and appreciate the comment!
Comments need special attention to be successful, though. Generally, you will have strict rules to follow. You can’t simply leave a “this was great, hey check out my site” comment. It will either be filtered for spam or it will be ignored. You need an insightful, detailed, and helpful message. You need to expand upon the topic in the post, argue against it, or support it with your own data. The point is to be valuable and attract positive attention.

However, this may not be the case for your company or your clients. You may start by looking at keyword rankings, and realize that you’re no longer ranking on the first page for ten of your core keywords. If that’s the case, you quickly discovered your issue, and your game plan should be investing in your core pages to help get them ranking again for these core keywords.
Go to local events or Meetup events and connect with bloggers in your industry. An example of an event I run to connect with bloggers and people in the online marketing word is: Make friends first and then try to gain guest posts later. I am not really a fan of websites which are flooded with guest posts one after another; it is the type of thing which Google is just waiting to target.
Mobile traffic: In the Groupon experiment mentioned above, Groupon found that both browser and device matter in web analytics’ ability to track organic traffic. Although desktops using common browsers saw a smaller impact from the test (10-20 percent), mobile devices saw a 50 percent drop in direct traffic when the site was de-indexed. In short, as mobile users grow, we are likely to see direct traffic rise even more from organic search traffic.
