Google Trends is great for research and planning, to analyse keyword demand and associated costs. It really does help plan to capture consumer demand. It can be a little tricky to use, as the UX design isn't brilliant, so you'll need to learn how to navigate the website.
SEOTesting.com is great in monitoring the results of implemented SEO optimisations. SEOTesting.com also has extensive content analysis reports that make it really easy to find long hanging fruits for content optimisation. However, I would not recommend SEOTesting.com for rank tracking and it has no tools for technical SEO. But if you pair SEOTesting.com with some other SEO tools of your preference, you get a really valuable toolset with decent pricing.
I love how Google Trends presents the popularity of a specific query by location. For example, my product may be more popular or more "searched" in a specific state or city. This helps a lot for direct mail campaigns or any sort of in-person marketing efforts like events or pop-ups. You could use the information from Google Trends to decide what locations will be more receptive of your product/industry or you could see where people have little to no interest and build a brand awareness campaign focusing on those areas.
Another great feature within Google Trends is that it shows "Related Queries", which are basically suggestions of better keywords or phrases to incorporate into your content. If you search for data on a keyword you're using that's too broad (your content won't stand out among other web pages) or too narrow (not many potential customers are searching that keyword or phrase), Google Trends will suggest a related keyword or phrase that is more appropriate or trending at the moment. You could go back and incorporate these phrases into your content so that it's more likely to be found on search engines.
Within the Google Trends "Related Topics" section, you can choose whether you want to see topics that are "Top" or "Rising". I like this feature because looking at a "Rising" topic can help you create content that's more likely to be seen - especially if you're a beginner. Most topics that are in the "Top" category can have thousands of web pages that you're competing against and you can feel like your content is drowning. But the topics in the "rising" category can be great for newer sites that haven't developed authority online yet. You can write on one of these topics and be one of the first sites to create content on that topic, which gives you a head start over other sites.
Google Trends "Categories" is also a great feature. If you don't have any content ideas for your website, you can easily find inspiration by selecting a category that's relevant to your industry. The top keywords or topics will come up and you can create content on those topics to increase your number of web visitors. For example, if you work in the fashion industry and you don't have content ideas, you can have Google Trends generate data for the "Beauty & Fitness" or "Shopping" categories to see what's trending. Google will tell you if a specific brand, person, or event is trending and you could write an article based on one of those trends. Since people are searching for that topic, your content will be seen. This is a great way to create timely content even if you're new to an industry or simply haven't kept up with it.
It would be nice to have breadcrumbs available so that I can go backward in a particular search. One I click a topic and then click the related terms two or three times, I find that I'm so far down the rabbit hole that the "Back" button in my browser is a really inconvenient way to find my way back to a certain stage of my search. If there were breadcrumbs I could jump directly back to a particular stage and chase another rabbit from there.
It's easy to get lost searching in here for an extended period of time. I would be nice to be able to print a report of my whole session when I have finished.
It would be nice to have a Top Tends board of job searches or other information related to jobs that are currently popular Google searches.
SEOTesting.com is NOT all-in-one SEO tool. But what it does, it does really well.
Rank Tracking requires to fill landing page per keyword. That doesn't make sense as the desired landing page is not always the best ranking landing page for each keyword.
Dashboards timelines should have some options to select only the desired timeframe. Then it would be sometimes easier to look at only the last two months for example.
Google Trends is very easy to use. you just search for a certain keyword or phrase, and it tells you how often that keyword or phrase is searched, where in the world it is searched, and over the last decade, how often it is per year.
The account person is quick to respond, though issues reported required support of other teams with no SLA. The data is easily comprehensible and the platform is incredibly versatile. Sometimes scanning problems take weeks to diagnose and fix. The learning curve for SEOTesting.com is minimal
I haven't needed to use any support for Google Trends. However, I've used Google's support in general and it's a hit or miss. Usually, there's a long wait or they don't understand my problem. They are the only ones that can help, so sometimes I feel stuck. They prioritize paying customers for sure.
Google Trends is a great place to start in the content curation, content research, blog post writing, and resource page creation process. It is not, however, a place to do serious SEO optimization. Tools like Moz, or Analytics SEO would be a better place to go after you do initial research on Google Trends to dial in your keywords, and optimize content for search engines.
SEOTesting.com is a very specific, focused too. It's not "better than" the other tools. It does something they don't do well: gets data from your SEO results out into an easily-read, easily-reported format so you can 1. learn from what's working and what's not 2. show your team what success & failure look like 3. demonstrate to your boss/client the short-run benefits of investing in SEO Search Console has all the data in it. In fact, SEOTesting.com gets its data from Search Console. But you are going to waste your time and your colleagues time if you try to monitor granular, week-by-week progress for different pages in Search Console. SEOTesting is awesome at that. Use Ahrefs and/or Semrush to get ideas on how to improve your website's content and tech SEO. Then make the changes. Then use SEOTesting.com to find out if it worked!
