Ever heard the saying that a picture is worth 1,000 words? Well, a video is worth 1.8 million, and YouTube is the best place to promote your video ad to an engaged audience. One of the most popular YouTube ad formats, TrueView ads, play before other videos on the site and allow users the option to skip after five seconds (and you don’t have to pay if a viewer skips your ad!). Since there is less competition on YouTube compared to other search engines, your brand has a massive opportunity to reach and convert a ton of consumers across a variety of different demographics.
"Cloaking" via IP delivery works differently from cloaking via "user agent". While IP address spoofing is harder than user-agent spoofing and more reliable, it is also harder to keep the list of IP addresses used by search engines for their crawlers up-to-date. An outdated list with active crawler IP addresses missing enables the search engines to detect the cloaking and may result in a removal of the site from the search engine's index.

Remember that martech landscape map with over 5,000 companies? Almost every product category is made up of over a dozen different players. You can’t reasonably expect to analyze all of them. You don’t need to either. An ideal competitor analysis includes three to five companies that represent the biggest threat to your business. (Go with five if you’re operating in a crowded market.)

Shakeups. As you analyze your competitive information be on the look out for broad management changes or changes in ownership. This is an indication that major policies and marketing shifts are on the horizon and you should anticipate changes. It may be a good opportunity to court your competitor's star employees. People often change jobs during management shakeups. 

Bonus Trick: Try typing in your basic keyword phrase, followed by every letter of the alphabet, and making a list of those phrases. If your product or service is specific to locations, try typing in those locations to see what kind of search volume exists. (Are alternative energy tax credits more commonly searched in Austin compared with Cleveland?)
When using the Keyword Explorer, Ahrefs will also produce the "parent topic" of the keyword you looked up, as you can see in the screenshot above, underneath the Keyword Difficulty meter. A keyword's parent topic is a broader keyword with higher search volume than your intended keyword, but likely has the same audience and ranking potential -- giving you more a valuable SEO opportunity when optimizing a particular blog post or webpage.
