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.
A variety of methods can increase the prominence of a webpage within the search results. Cross linking between pages of the same website to provide more links to important pages may improve its visibility. Writing content that includes frequently searched keyword phrase, so as to be relevant to a wide variety of search queries will tend to increase traffic. Updating content so as to keep search engines crawling back frequently can give additional weight to a site. Adding relevant keywords to a web page's meta data, including the title tag and meta description, will tend to improve the relevancy of a site's search listings, thus increasing traffic. URL normalization of web pages accessible via multiple urls, using the canonical link element or via 301 redirects can help make sure links to different versions of the url all count towards the page's link popularity score.
Organic traffic, on the other hand, are those visits which are tracked by another entity — usually because they have arrived through search engines — but also from other sources. Hubspot’s definition emphasizes the term “non-paid visits,” because paid search ads are considered a category of their own. But this is where the lines between direct and organic start to get little blurry.
Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
