Ahrefs

This is a very comprehensive tool in terms of ability and information it provides. While it won't give you every link a site has, it will give you most of them and will provide you with the most up to date link information for any site compared to all of the other link crawl providers.

If you have a marketing department that wants to be agile and measure valuable goals for your company, then GTM is the way to go.You will be able to track almost any event of value that you want on the site (without adding any extra code, thanks to auto-event listener), add new marketing tools if needed in minutes and send events to multiple platforms. This has huge value for your company if you think about it: measuring your efforts quickly and changing course if it is not working can save tons of money. I believe almost anyone who has a site on the internet can benefit from it because of how much time it saves (considering it's even free!).Just beware: GTM opens the door so you can add any piece of code you want. Someone without much experience can overload the site or affect site speed

Pros

  • I love how Ahrefs Site Explorer includes a list of the broken links to a site, the backlinks pointed to these broken links, and the date these broken links are found. It makes identifying quality 404 error pages so much easier, especially when we have the option to download a file with all this information.
  • I love how we can gauge what the top content and top pages are for any website using Ahrefs Site Explorer. Assessing the top content and pages on a website provides insight into what we can do to amp our content strategy.
  • I also like the anchors cloud function on Ahrefs Site Explorer, because it's a clear overview of what anchor texts are most prominent for a given website, and allows us to make adjustments if there's a lack of anchor text variety.

  • Code injection is simplified with Tag Manager. Facebook Pixel, Google Analytics, Marketo Munchkin, HubSpot tracking, Hotjar, CallRail, the list goes on. One stop, no constantly bugging the devs to install new code.
  • Need to track onsite events? Build a single listener or trigger, and apply that trigger to countless different applications. A user form fill can trigger an AdWords and Facebook conversion, tag a Hotjar recording, signal deployment of a pop-up or just about anything else javascript-driven.
  • GTM is basically coding light. For non-developers who might be terrified of GitHub, it makes features like version control, forking/branches and draft / deploy mode approachable.

Cons

  • Ahrefs Site Explorer provides an overview of domain health and the issues that can be fixed, and sometimes the suggested "critical issues" can be an astronomical number and not accurate.
  • For certain features on Ahrefs Site Explorer, there can a more elaborate description/guide on how to utilize the feature.

Ahrefs recently became more expensive. While they offer a large web index of backlinks, some of the modules of analysis available in similar tools make them a better value in many respects. Ahrefs continues to update their interface, but the accuracy of link counts and new/lost data modules calls into question the validity of the provided information.

Google Tag Manager has some strong capabilities in simplifying the addition of features and analytics to a site. However, it can obscure code making it difficult to debug problems. It also allows changes to the site that can break certain it for browsers. With great power comes great responsibility.

Usability

Based on 1 answer
Ahrefs is very easy to use - you can jump right in and understand most of the assets. Overall, the dashboard snapshots give a very good picture of inbound link activity. For deeper analysis of historical trends, the system can become cumbersome, making it hard to do full work without exporting and reformatting the data.

Google Tag Manager, like other Google products, is focused on user-friendliness. All buttons are clearly labeled, documentation is thorough and plenty of tutorials exist to help answer any questions. The layout and menus in Tag Manager are clearly labeled and consistent with other Google products.

It depends wether you are seeking official support from Google itself, in which case it would be rated very low because it's not their business model, they would rather have you work with one of their Google Analytics Certified Partner (GACP).In terms of self-served support, Google offer extensive documentation at https://developers.google.com/tag-manager/, recently revamped training (https://analyticsacademy.withgoogle.com/course05/preview), has active forums and user community (https://plus.google.com/u/0/communities/104865292981489764063) which can typically answer even the most advanced questions.

I thought there was a little bit too much emphasis on AdWords stuff, not enough on the generic application of GTM.

Planning and communication will help greatly with an in-house implementation. If there are large teams, try to limit the number of people involved to 1-2 developers (back-end dev may be necessary depending on your platform), one analytics marketer and one project manager.

Alternatives Considered

Each of these tools has advantages over the other. Ahrefs link counts are often considerably higher than Moz or Majestic, which could be indicative of a larger web index or inaccuracy in filtering old links. Ultimately, we use all of these tools to be able to take advantage of the different proprietary analysis modules that they each offer.

I have not worked enough with Adobe Analytics to provide a comparison between GTM and Adobe Analytics

Return on Investment

  • Ahrefs allowed us to build smarter SEM strategies and estimate how we ranked against competitors for web traffic
  • Ahrefs' impact on revenue is difficult to measure because it is one tool in a larger suite. Alone, it does not drive leads but supports the efforts of a team to grow traffic.
Amanda Tessier profile photo
  • Improved user experience index - By tracking user interactions we are able to pinpoint UX shortcomings and fix them
  • Improved CR and ROI on media campaign - With enhanced ecommerce tracking through GTM we are able to get much more information about our e-shop checkout process, and identify shortcomings and performing media channels
  • Cheaper and faster implementation of third-party functionalities. Adding third-party scripts does not need to go through the usual development process
