You thought we’d start this off with Google Analytics, didn’t you? Google has an excellent suite of tools, but don’t count Bing out.
Top features include keyword research tools and thorough reports. Keyword suggestions are usually spot-on, too.
Google may be master of the search engine universe, but Microsoft’s Bing analytics has steadily gained ground. In the United States, Bing’s market share has grown by 15% over the last decade, which makes Bing now second only to Google in the country.
Google Analytics - Best SEO Tools

2. Google Analytics

Google Analytics offers a complete suite of useful products, so it’s hardly surprising that it’s one of the most popular free analytics tools on the market. GAs gives you metrics on how many visitors your site receives, where they come from, how long they stayed, and more. This information helps you to monitor every aspect of your site.
Google Data Studio

3. Google Data Studio

The handy tool merges all your data from Google Search Console and a range of other applications. Its most useful feature allows you to create custom dashboards so that you can monitor the data that you want to use in neatly summarized sections.

You’ll appreciate the Chrome extension if you want to see what aspects affected your traffic. It has numerous useful features, like a pop-up note that tells you what might have affected the traffic in that way.

Google Search Console  - Best SEO Tools

5. Google Search Console

Google’s search console is another tool that is ideal for finding the right keywords. It’s also one of the best free seo tools for learning more about your page rank and how Google crawls your website.

Optimized Indexing

6. Link Redirect Trace

Another Chrome extension, this tracer is a useful tool for analyzing link metrics in particular. The extension scans a site and lets you see the value of each link. You’ll see the page rank of the linked website and redirect page.
It will also alert you to broken links fast. Broken links not only frustrate the visitors that click on them, but they also get you into trouble with search engines. If a webmaster can’t keep the links on their site current, what else might they have overlooked?
Screaming Frog

7. Screaming Frog

Screaming Frog is a handy tool since the free version offers you 500 URLs in each crawl (that’s plenty for most people). You’ll see a range of details for each URL, and the metatag data is fantastic when you need to craft a killer meta description. It may not be one of the best seo tools for crawling a site, but it’s definitely one of the best free seo tools for this purpose.

Researching Keywords

Moz Keyword Explorer - Best SEO Tools

8. Moz’s Keyword Explorer

Moz was one of the industry pioneers when it came to SEO, and it isn’t shy about sharing knowledge either. Your free account allows you ten full search queries monthly, which is more than enough information for most webmasters.
The most useful features include the monthly search volume, the click-through rate, and the keyword difficulty score for your selected keyword tool.

The range of data is limited, but it’s more than enough for the average user to analyze the backlinks of a site.

We were hesitant to add this tool because most people don’t use it properly. If used judiciously, though, it can help you clear up your website’s image against optimization mistakes, like negative SEO.
Don’t be overzealous with the tool and read through Google’s guide before you commit to disavowing any links.

12. Link Miner

Link Miner is a simple extension that allows you to find broken links on a page quickly. It won’t impress someone who wants pages of data, but it’s unpretentious enough for beginners to use easily.

Ahrefs’ free tool whets your appetite for the paid version, but it is a great option for those who have a stretched budget. You can’t expect the same features as the paid version, but it will allow you to check up to 100 links, which is a great start. While the free version may be one of the best free seo tools available, the paid version is currently the best tool for backlinks period.

Local SEO

Google My Business

14. Google My Business

If you’re hoping to end up on top of the page for local searches, claim your Google My Business page immediately.
GMB puts you in the driver’s seat and allows another opportunity to showcase your business. Without it, you can’t answer reviews posted on Google about your business, for example.
Considering that it’s a free tool by the ‘big daddy’ of search engines, it makes sense that maintaining these pages is an integral part of improving your page rank.

Happy clients are usually more than willing to leave a review if it is easy to do. Create a link with this app as a straightforward reference point for clients to add or read reviews.

16. Moz Local Check Business Listing
