The tool returns a wheel of questions. These are organized into types and color-coded by search volume.

You could choose the questions people ask the most to guide your content strategy.

Best SEO Software from Google

We all know Google dominates search. So, it’s smart to use its proprietary SEO software to gain access to the most insightful, up-to-date data on your campaigns.

Below are three of the most useful Google SEO tools:

1. Google Analytics (GA)

Google Analytics 4 (GA4) connects to your website to provide accurate information about how it performs in paid and organic search.

For example, in the screenshot below, you can see that 58,000 new users visited the site between January 17 and February 13. It also shows the total revenue the site generated ($79,000) in that period.

That information (much of which is only on GA) is essential for measuring the effectiveness of your SEO campaigns. Or even one-off changes to your site geared toward improving traffic.

Tip: Learn more about GA’s latest version, GA4, on Semrush’s free GA4 course with SEO expert Jeff Sauer.

Notable features: GA4 lets you extract a huge amount of insightful data on:

• Users
• Sessions
• Page engagement
• Traffic sources
• And more

You can also implement Application Programming Interfaces (APIs) to collect data from various sources and integrate it with other Google products.

How this software can help your business: GA reports should guide your strategy. Use them to understand the effects of your actions, fix inefficiencies, and repeat winning patterns.

Cost: Free

2. Google Search Console

Google Search Console (GSC) is one of the best SEO tracking software out there. It monitors how your website appears on Google over a period of time. It also helps you fix indexing and crawling issues.

To help Google better understand your web pages, submit sitemaps and individual URLs for it to crawl. This gives your content a better chance to show up in search engine results pages (SERPs).

GSC, formerly Google Webmaster Tools, also shows you which search terms bring the most traffic to your site. That way, you can optimize your content accordingly.

For example: You see that most visitors look for information on “cat food nutrition.” You could create more content around that topic. Or target buyers with relevant Google Ads.

Notable features: GSC’s accessible reports: 

• Make sense of technical search and SEO data 
• Are easily shareable so you can keep colleagues and stakeholders up to date

How this software can help your business: GSC is the easiest way to give Google the information it needs to see, understand, and rank your website. It shortens the time between when you publish content and when it shows up in SERPs.

Cost: Free

3. PageSpeed Insights

PageSpeed Insights analyzes your website’s performance and recommends ways to increase its speed. 

Fast loading speeds improve the user experience (UX) and contribute to higher rankings. Google itself confirmed speed as a ranking factor a while back.

That makes PageSpeed Insights one of the best SEO ranking tools for your toolkit.

The analysis tool uses technical metrics called Core Web Vitals to gauge performance. It then gives an overall verdict on whether the site meets visitor expectations.

Here, the Semrush desktop site passes the assessment comfortably:

Check below the first dashboard for improvement opportunities.

Notable features:

• See improvement opportunities for mobile and desktop sites 
• Freely check competitors’ URLs to see how you compare

How this software can help your business: PageSpeed Insights’ data and recommendations helpyou stay on top of site performance issues and maintain search performance.
