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. 

This is both a challenge and a great opportunity. The challenge is because the organic spots aren’t what they used to be – there used to be ten organic spots on the first page to compete for – and only five above the fold, (which refers to the vertical limitations of a user’s screen and the amount of content one can view without scrolling). Now there might be local search results, news releases, images and video included in the results – many of those above the fold. What’s the new number one spot? Is it the first local result, news release, or organic listing?

To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots. When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam.[46]
While you are updating your website’s copy, you’ll also want to implement changes in your HTML – specifically, in your H1 and H2 title tags, as well as your meta descriptions and URLs. You’ll want to put your most relevant keywords in these sections of your website HTML. Search engines take into account the words in these sections of your website’s HTML when listing out relevant webpages in a search result.
You also should not underestimate the impact that organic search can have on the success of your website. Our research here at BrightEdge has found that about 51 percent of the traffic on the average site comes from the SERPs. In other words, more people land on your site because of the results pages for particular queries than because of your email, social media, and paid marketing efforts combined.

As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.
At the end of the day, webmasters just need to know their sites: chances are your analytics tool is more like a person than a software package, and will classify traffic in irrational ways. I’ve stumbled across website traffic originating from diverse and confusing sources being classed as direct — often requiring a considerable amount of thought and exploration to work out what is happening.
In my opinion, for many business owners new to the world of digital marketing, there is often a common misconception that SEO and social media are separate entities, each operating in their own world with distinct goals. SEO and organic social media marketing work together to create value and provide relevance for your audience. Any good digital marketing strategy should do its best to have both SEO and social media working together, in tandem.
Google is moving into more and more aggressively commercial spaces, like jobs, flights, products, all of these kinds of searches where previously there was opportunity and now there's a lot less. If you're Expedia or you're Travelocity or you're Hotels.com or you're Cheapflights and you see what's going on with flight and hotel searches in particular, Google is essentially saying, "No, no, no. Don't worry about clicking anything else. We've got the answers for you right here."
There are also a few more similarities. All of these marketing methods are measurable to an extent never seen in any other media. Every click can be measured – where and when it came – and followed through to the conversion, the sale and the lifetime customer value.  This feedback loop creates optimization opportunities that can create huge incremental improvements in your SEM campaigns.
One of the most enduring misconceptions about search engine marketing is that whomever has the largest advertising budget wins. Although a larger advertising budget can certainly be advantageous, especially when targeting highly competitive keywords, but it’s far from a requirement for success with search engine marketing. This is because all ads go through a process known as the ad auction before appearing alongside search results. For the purposes of this explanation, we’ll be focusing on the ad auction in Google AdWords.
SEO is not an appropriate strategy for every website, and other Internet marketing strategies can be more effective like paid advertising through pay per click (PPC) campaigns, depending on the site operator's goals. Search engine marketing (SEM), is practice of designing, running, and optimizing search engine ad campaigns.[55] Its difference from SEO is most simply depicted as the difference between paid and unpaid priority ranking in search results. Its purpose regards prominence more so than relevance; website developers should regard SEM with the utmost importance with consideration to PageRank visibility as most navigate to the primary listings of their search.[56] A successful Internet marketing campaign may also depend upon building high quality web pages to engage and persuade, setting up analytics programs to enable site owners to measure results, and improving a site's conversion rate.[57] In November 2015, Google released a full 160 page version of its Search Quality Rating Guidelines to the public,[58] which now shows a shift in their focus towards "usefulness" and mobile search. In recent years the mobile market has exploded, overtaking the use of desktops as shown in by StatCounter in October 2016 where they analysed 2.5 million websites and 51.3% of the pages were loaded by a mobile device [59]. Google has been one of the companies that have utilised the popularity of mobile usage by encouraging websites to use their Google Search Console, the Mobile-Friendly Test, which allows companies to measure up their website to the search engine results and how user-friendly it is.

Step #3: Calculate your ROI based on the right performance indicators The performance indicators will depend on the objective you selected in the first step. Want to generate leads? You could track your new subscribers. Want to increase engagement? You could track clicks, comments, shares, etc. Let’s go with the first example: Your goal is customer acquisition. You’ve already set up tracking for sales conversions. It’s time to dissect your organic search traffic.

Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
