Another tip you can use is just reach out to the prior agency and say something like the following: “We realise you were using link networks for our website which has resulted in a Google penalty and loss in business. Can you please remove my website from any link network you have built?”. If the prior agency is decent, they will remove the links from the network.
However, while bidding $1,000 on every keyword and ranking #1 for every relevant search sounds nice in theory, most businesses have to play a balancing game between ranking higher and paying too much for clicks. After all, if it costs $17.56 to rank in position #1, but you can only afford to pay $5.00 per click, bidding $1,000 on a keyword to guarantee yourself the #1 position would be a great way to bid yourself out of business.
Optimize for opt-ins. Make sure you lead to something more than your content. What this means is that when people read your content, they must know where to go next. This may come in the form of a call to action or your offering of additional content, appearing perhaps as a PDF. Growing organic traffic is important, but it doesn’t matter if you are not converting those viewer into leads. Your business doesn’t pay its bills using raw traffic.
SEO techniques can be classified into two broad categories: techniques that search engine companies recommend as part of good design ("white hat"), and those techniques of which search engines do not approve ("black hat"). The search engines attempt to minimize the effect of the latter, among them spamdexing. Industry commentators have classified these methods, and the practitioners who employ them, as either white hat SEO, or black hat SEO.[49] White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.[50]
Thanks for the comment Slava good too see your team is on top of things and happy you liked the post. The website in the case listed was a client who has taken on an agency who was doing lower quality SEO work which was affecting the site such as the huge link network and a strategy which only revolved around mainly head terms. We saw no long tail integration from the old agency's strategy, so we were able to yield great results to begin with. The clients site has 100's of high quality articles which we were able to re optimize and update as noted. Further to this they had a large index of high quality pages to work from. Sure enough the points listed above were key elements to a far wider strategy which could be 100's of points. I just wanted to include some of the biggest wins and easy to implement points.  

Basically, what I’m talking about here is finding websites that have mentioned your brand name but they haven’t actually linked to you. For example, someone may have mentioned my name in an article they wrote (“Matthew Barby did this…”) but they didn’t link to By checking for websites like this you can find quick opportunities to get them to add a link.

PPC gives you the ability to fix your daily budget depending on how much you’re willing to spend. And since you can start off with a small amount, you don’t have to put a heavy investment at stake before testing the waters. Once you know a certain campaign is giving you a good return on investment, you can ramp up your budget and increase your ad spendings without worrying about incurring losses.

Because so few ordinary users (38% according to Pew Research Center) realized that many of the highest placed "results" on search engine results pages (SERPs) were ads, the search engine optimization industry began to distinguish between ads and natural results.[citation needed] The perspective among general users was that all results were, in fact, "results." So the qualifier "organic" was invented to distinguish non-ad search results from ads.[citation needed]
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.
