We at SEMrush continuously monitor Google’s updates, as the search engine rarely stands still. While testing the updates that are most likely to impact advertisers, we have come to the conclusion that Google is moving in the direction of “autopiloted” campaigns. The message is clear, the more you delegate to Google Ads’ artificial mind - bids, placements, banner sizes, etc. - the more benefit you and your customers will get from the campaign.

Research: These searchers are further down the funnel than informational searchers. They’ve already decided that they want to buy a product, but they haven’t quite decided which one is best. They’re looking for more information, so product keywords usually include words such as "review", “top 10”, “comparison”. And while it may look like spam to you, a word like “cheap” can actually help turn researchers into conversions.
Example 2: If your goal is B2B marketing and relations, your keyword(s) should have a revenue spin. For example, if your business sells software for eCommerce, your keywords would focus on that. Your concept might sound something like this: “the best software for B2B marketing and eCommerce.” You would then create a keyword theme around this concept, leading to use of the keyword or phrase for B2B SEO. This specific keyword concept is more likely to attract your target audience of B2B marketers and companies.
Keyword Difficulty (KD). This is a cumulative score that shows you how difficult it will be to rank organically for this keyword. It accounts for the number of competitors within this space as well as the strength of those competitors. If one of your competitors is a government website that gets millions of visits each month, for instance, that will impact your difficulty score. Other factors that impact difficulty include the quality of content your competitors have and how relevant it is to the searcher.  As a best practice, look for keywords with a difficulty score that's no higher than 80.
Now the ad servers don’t create this table themselves, they license it from another ‎company like MaxMind or DigitalEnvoy, whose primary business is geolocation ‎data.   This is no enviable task; IP addresses themselves don’t necessarily have an ‎obvious pattern in the way they are assigned like a telephone area code would.  It’s ‎a bit like solving a mystery, and the geolocation companies use a variety of ‎methods to approach the problem.  ‎ /injects>
