This emphasis on competition is related to the advent of game theory in the mid 20th century around the same time. The problem is that game theory is one mental model of many to help make decisions, not the only one (Ben Thompson from Stratechery has a good post on the Prisoner’s Dilemma that is a fundamental one). Even researchers are starting to point to the fact that there are no perfect solutions (such as a Nash equilibrium) to most situations.
…Well, this is a best practices post, right? It may seem obvious to use the highest converting ad formats in your PPC campaigns to boost their conversion rate, but many marketers don’t actually know what these optimized ads look like—nor that they can do the optimizing themselves even after their ads go live! In this next section, we’ll break down a few important ad formats and options that you should have on your radar and use to maximize your conversion potential:
The distinctions here can become quite urgent depending on the kind of product you’re selling or the kind of customer you’re looking to find. If you’re trying to find people who are interested in selling their homes in the East Village, then you don’t want to target people who are just in the East Village on their spring break or while visiting family. If you’re trying to target high net worth individuals on vacation in Montauk, New York because you believe they’re ripe targets for ads about buying beachfront houses in Montauk, then you don’t want to waste your ad spend showing ads to locals.
A competitor's media strategy reveals budget allocation, segmentation and targeting strategy, and selectivity and focus.[13][14] From a tactical perspective, it can also be used to help a manager implement his own media plan. By knowing the competitor's media buy, media selection, frequency, reach, continuity, schedules, and flights, the manager can arrange his own media plan so that they do not coincide.

Long tail keywords are longer word phrases. They are specific phrases searchers are more likely to use when doing a specified search.  Due to the more tailored nature of long tail keywords, it is important to create a theme around these phrases. Doing so will increase your business’ rank in search engine results. A generic single keyword is not as valuable as multiple keywords that match a user’s search. In short, long tail keywords prove that, as far as B2B SEO goes, less is not always more. Once you’ve compiled a list of “long tail keywords” that describe a certain theme, you can begin conducting your keyword research.

Michiel wrote about Homepage SEO, telling people not to try and rank their homepage for a specific keyword. In the comments there were clearly some misconceptions about how branding relates to your keyword strategy. We’ve been writing a lot about keyword research lately but we’ve not talked about keyword strategy much, so this post elaborates on what these are and how they connect to each other.
Finally, some strategies will drive both efficiency and growth within an account. For example, concluding an ad copy test based on CTR, conversion rate, or conversion per impression can increase revenue and improve ROI. However, these strategies typically show incremental long-term improvements, and are less likely to ramp revenue or improve ROAS in the short-term.

Keywords are the words and phrases that people type into search engines in order to find what they're looking for. By extension, they also describe what a piece of content (or an entire website!) is all about, and they're the words at the heart of on-page optimization. They still play an important role in a site's ability to rank, so by identifying the right words and phrases to target you can have an outsized impact on achieving your SEO goals.
Newspaper and Magazine ArticlesArticles in newspapers and magazines are a source of information you can use to get an idea of what your competitor is planning for the future, how their organization is run, and what new product information or innovations they have. Journalists may also uncover and reveal unflattering information about your competitor that may prove valuable to you. Be on the lookout for product reviews in magazines; they will reveal a competing product's strengths and weaknesses. Visit a college or public library. The reference librarian will show you how to find pertinent articles online much more quickly and easily than you'll find them by browsing.  
Even more specifically, I’m talking about Google AdWords—the major player in this space—and Bing Ads, the next largest network of its type, which also handles PPC ads on Yahoo. AdWords and Bing Ads operate so similarly that the differences between them won’t affect the advice in this post. For practical purposes, when you’re just starting out, you can think of Bing Ads as a mini AdWords: smaller in terms of traffic but also in terms of cost, which can be appealing.
This broken-link checker makes it easy for a publisher or editor to make corrections before a page is live. Think about a site like Wikipedia, for example. The Wikipedia page for the term "marketing" contains a whopping 711 links. Not only was Check My Links able to detect this number in a matter of seconds, but it also found (and highlighted) seven broken links.
