Hi SEO 4 Attorneys, it could be any thing is this for your site for a clients site.It could be an attempt at negative SEO from a competitor? The thing is people may try to push 100's of spammy links to a site in hopes to knock it down. In the end of the day my best advice is to monitor your link profile on a weekly basis. Try to remove negative links where possible if you cant remove them then opt for the disavow tool as a last resort. 
So, you have downloaded your links profiles on a CSV and you now have an extensive list of all your linked domains. If you have been doing SEO for 8+ years like me you can probably just know from analysis which links are bad from a TLD and URL point of view. If you do not know too much you can use tools such as Link Detox: http://www.linkdetox.com/ to complete analysis of your link profile. I would always consult the advice of an expert SEO in this instance because it is easy for these tools to mistake good and bad links.
We are in the SEO industry for a while now, wearing many hats: digital marketers, tool developers, advisers, researchers, copywriters, etc. But first of all, we are, just like you, site owners. And we’ve been through ups and downs regarding organic traffic, and we were in the situation of trying to understand why the Google traffic dropped dramatically at some point as well. Having all these in mind, we’ve thought of easing your work, and we’ve put together a list with the top 16 reasons that can cause sudden traffic drop, unrelated to Google algorithm changes or penalties.
This is a breath of fresh air. Information Technology has been, for too long, plagued by those exploiting the ignorance of well intentioned people. The more good gen we have the better we will do and the better services will become. We put useful information on our web site for people wanting to start up renting out cottages. It is extensive and quite annoys our rivals who keep this sort of thing secret, only giving it out if you 'send for an information pack'. This, then, gives them the green light to pester you with sales calls and threatened sales visits. Generosity with information is the way forward. People remember it and associate it with a postive attude towards business relationships. Thank you for your help with these links.
Hi Brankica Wow, this is a super-comprehensive list for me to go through one by one and try those I have not even heard of till now :-) As always, some very useful information for those of us serious about our traffic generation and making an impact in our niche. Thanks for sharing your own experiences and I'll let you know how I go when I have implemented some of your suggestions. Patricia Perth Australia
Brankica Great post. Looks like I've got a few weeks worth of exploring to do - checking out these blog traffic boosting tools and ideas! One question I have: How do you measure the success of each of these tools and tips? Surely you have tried some that were less successful than others. Do you track metrics and weed out the less-than-stellar time-suck ideas? I'd love to hear how you settled on these that you mention in the post. Perhaps there's value in talking a bit about the ones that have fallen by the wayside and why as well.
It increases relevancy: Siloing ensures all topically related content is connected, and this in turn drives up relevancy. For example, linking to each of the individual yoga class pages (e.g. Pilates, Yoga RX, etc) from the “Yoga classes” page helps confirm—to both visitors and Google—these pages are in fact different types of yoga classes. Google can then feel more confident ranking these pages for related terms, as it is clearer the pages are relevant to the search query.

To sum up all of this information, even organic traffic, like direct traffic, has some gray areas. For the most part, though, organic traffic is driven by SEO. The better you are ranking for competitive keywords, the more organic traffic will result. Websites that consistently create content optimized for search will see a steady increase in organic search traffic and improved positioning in the search results. As a marketer, it is important to look at your keywords and high-ranking pages to identify new SEO opportunities each month.
