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.
This is also where you can see Google's ML algorithms at work. Powered by Google Cloud Platform, the way Quick Answers and Featured Snippets are extracted gets increasingly smarter as Google introduces new innovations in deep learning and neural networks. These constantly evolving algorithms are baked into how the search engine surfaces information.
Robots.txt is not an appropriate or effective way of blocking sensitive or confidential material. It only instructs well-behaved crawlers that the pages are not for them, but it does not prevent your server from delivering those pages to a browser that requests them. One reason is that search engines could still reference the URLs you block (showing just the URL, no title or snippet) if there happen to be links to those URLs somewhere on the Internet (like referrer logs). Also, non-compliant or rogue search engines that don't acknowledge the Robots Exclusion Standard could disobey the instructions of your robots.txt. Finally, a curious user could examine the directories or subdirectories in your robots.txt file and guess the URL of the content that you don't want seen.
An SEO expert could probably use a combination of AdWords for the initial data, Google Search Console for website monitoring, and Google Analytics for internal website data. Then the SEO expert can transform and analyze the data using a BI tool. The problem for most business users is that's simply not an effective use of time and resources. These tools exist to take the manual data gathering and granular, piecemeal detective work out of SEO. It's about making a process that's core to modern business success more easily accessible to someone who isn't an SEO consultant or expert.
These cloud-based, self-service tools have plenty of other unique optimization features, too. Some, such as AWR Cloud and Searchmetrics, also do search position monitoring—which means tracking how your page is doing against popular search queries. Others, such as SpyFu and LinkResearchTools, have more interactive data visualizations, granular and customizable reports, and return on investment (ROI) metrics geared toward online marketing and sales goals. The more powerful platforms can sport deeper analytics on paid advertising and pay-per-click (PPC) SEO as well. Though, at their core, the tools are all rooted in their ability to perform on-demand keyword queries.
Depending on your topic / vertical and your geographic location the search engines may have vastly different search volumes. The tool can only possibly offer approximations. Exact search volumes are hard to find due to vanity searches, click bots, rank checkers, and other forms of automated traffic. Exceptionally valuable search terms may show far greater volume than they actually have due to various competitive commercial forces inflating search volumes due to automated search traffic.
Using Dr Dave Chaffey's approach, the digital marketing planning (DMP) has three main stages: Opportunity, Strategy and Action. He suggests that any business looking to implement a successful digital marketing strategy must structure their plan by looking at opportunity, strategy and action. This generic strategic approach often has phases of situation review, goal setting, strategy formulation, resource allocation and monitoring.
