Google Trends is appropriate in so many scenarios, but I definitely suggest it for content ideas and inspiration. Many people utilize it after already writing their content to add in popular phrases or words, but that is not enough. The platform should be used prior and during the content creation process so that you can use the data to see what your audience/customers are interested in at the moment and create the content based on their interests. It can help, but I find it much less appropriate to use it after your article, eBook, etc. is already written. Maximize on this useful tool by ensuring the topic you're writing about is relevant in the first place before simply adding in popular keywords. An article that's written based on what's trending will be far more successful than an article that solely has popular phrases added to it.
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.
Google Trends shows me geographic locations where a particular topic may be useful for advertising.
Google Trends allows me to drill down into those locations to metro and city levels where I can focus on exactly what local business clients need to know.
Google Trends allows me to identify and qualify search terms that my client's need to optimize their websites and social media content for.
Google Trends shows me what people are talking about in a specific location over a specific period of time. This is a great way to know what I should be posting on social media.
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.
Overall I think that Ahrefs is a better product when it comes to really drilling down and getting all the data that you need in order to understand a given behavior or problem. Ahrefs is much more powerful in its feature set but does not have the same level of overall data/visual data representation that Google Trends does.
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!
