If you’re here, it’s because you know you lose hundreds of thousands of dollars every day to your competitors.

Prospects don’t know you exist.

What’s worse, neither does Google (or Bing).

But you can change that in a matter of days to months with an SEO strategy (Search Engine Optimization), a handful of SEO tools, a small chunk of your content marketing budget, and a hells yes attitude.

Before you know it, your competitors will see you climbing up the SERP ladder (search engine results pages), hot on their heels to take your place on Google’s visibility stage—the coveted first page of SERP.

When you tackle SEO, do so with gusto, and make every decision knowing that customers want two things:

  1. A solution for their problem
  2. The easiest way to solve it.  

It’s not just that they need to fix something. It’s that they want to spend the least amount of time fixing it.

People take the easy route, so make yourself the easy route. 

If you stand in your potential customers’ shoes, here’s how they see things:

  • They want a list of options to show up in SERP when they google their problem. Make sure you’re on that list. 
  • They want an obvious link to stand out. Make your snippet sparkle.
  • They want to click that link, like what they see on the landing page, and buy their worries away. Make sure your SEO is in bed with your CRO (more on that later).

There are hundreds of SEO tools that get that job done. 

Not surprisingly, a lot of them aren’t worth using, or they look like they were designed in 1988.

We’re going to do better than that. 

The good news is, you only need a handful of powerful SEO tools to keep your SEO work sensational. 

We’ve scrubbed the corners of the internet and put our top 50 picks right here—with one giant caveat: we dedicated an entire post to SEO keyword research tools, and you’ll find every tool worth its keyword salt over there

In this post, we’ll focus on all the other SEO tools and what they do.

What do SEO tools do?

Search engine optimization tools prepare your content to pass Google’s algorithm criteria so it ranks well on SERP. 

SEO tools optimize four different things:

  1. Content (for Google, social media, WordPress, etc.)
  2. Technical SEO issues (page speed, code errors, redirects)
  3. Links (backlinks and link building)
  4. Keywords (covered in-depth here)

Optimizing these four things has a lovely side effect: visibility. 

Visibility today depends on SEO (search engine optimization). 

Get SEO right, and you make money. Making money is funner than losing it, so we take SEO seriously. Taking SEO seriously means using SEO tools to get you on the playing field (like a streaker running naked in front of thousands of fans).  

Let’s start by taking a quick look at the why behind the what because it’s good to know the landscape before you build a house on it. 

Why is SEO even a thing?

4.66 billion people around the world today use the internet. That’s 60% percent of the global population. 9 out of 10 of those 6 out of 10 people surf over 1.2 billion websites (and counting) with their phones every day.

That’s why SEO is a thing.

50 best SEO tools - use of internet stat
4.66 billion people use the internet around the world in 2021—Source

Without SEO to steer organic search traffic and paid traffic your way, how would you ever get your page to show up on a handful of the 4.66 billion phones worldwide? How would you let people who need what you have know about your cool stuff and ultimately buy it?

You wouldn’t. 

Your landing page or blog post would be buried behind billions of other pages. 

But SEO is a magical digital marketing gem that narrows the playing field. 

And SEO tools make that gem sparkle.

But which tools?

Well, you’re welcome for making that part easy because we’ve listed 50 of the best SEO tools right here in one spot. 

Some are paid, most have free trials, and a few are completely free SEO tools.

So if you’re stressed out about SEO tools, go ahead and remove your shoulders from your ears. This sort of thing is fun once you get the swing of using apps to get some eyeballs on your stuff. 

It’s a strategy that gets you a bigger ROI if you make the right choices.

SEO is like playing Risk

Think of SEO like playing Risk, “The Game of Strategic Conquest.” You have a limited number of infantrymen and cavalry you can place on the board. You place your men (keywords) and, in some places, you also place cavalry (PPC bids). 

You might segment your forces (Single Keyword Ad Groups) to increase your odds of winning the battle for that particular country (search term). 

Some battles will eat away at your troops (high CTR without ROAS) and you’ll retreat and regroup to fight another battle when the terrain is more favorable (better CRO). 

You’re always looking for the high ground (the best optimization) so you don’t get outflanked, just like you’re always vying for the right customers to click your links over your competitors’ links (outrank them). 

You maneuver to align your offer with customer queries FOR TOTAL WORLD DOMINATION.


There are two sides to the conversion universe. 

When it comes to SEO, you do the research once but you apply the results to both sides: SEO and PPC (otherwise referred to as organic and paid marketing). 

  1. Organic SEO (Search Engine Optimization) focuses on driving the needle up over time with valuable content. It’s free, but you won’t see dividends for months.
  2. Paid SEM (Search Engine Marketing) focuses on an immediate payback by bidding on keywords that drive ad campaigns. Every click (CPC) costs money, but you know pretty fast if you won a return on your ad spend (ROAS).

SEO and PPC blend together in a magnificent marketing melée that results in a higher overall ROI than if the whole were separated from its two parts.

Whichever universe pays your salary, anyone with a serious game face pulls data from multiple tools to see the bigger SEO picture (and the smaller SEO corners).

If your blog posts and landing page copy aren’t in line with the keywords you’re trying to rank for, your efforts won’t be as effective as they could be.

People find you in search because of your SEO. But people share your stuff because they adore your content. 

Once you have a solid SEO strategy, the work of making sure your content is optimized isn’t that hard

There are apps/tools for that. 

There are also tools that link your content to other great content and tools that track how your SEO is performing—including your video SEO.

First, we’ll start with the all-in-one tools that cover almost everything. These are powerful tools if you have the budget. 

Then we’ll look at some single-purpose SEO tool dynamos. 

As we go, we’ll round out our list with freemium and lesser-known alternatives. 

At the end, we’ll look at dashboards and reporting tools.

Get your game face on. 

Content optimization and tracking tools

These SEO tools look at the technical aspects of your site: on-page optimization, page speed, page rank tracking, duplicate content, missing page elements (like robots.txt file, XML sitemaps, no/follow, no/indexing etc.). But they also analyze how you’re doing versus your competitors and how you’re doing socially.

The technical fixes improve your SEO performance which boosts your rank so you’re seen more and shared more often (than your competitors).

These tools will tell you if your traffic has dropped and what long-tail keywords or backlinks might get more visitors. 

Let’s start with the big guys.

All-in-one SEO Tools

If you want one big, beautiful, comprehensive, does-it-all SEO tool—sorry, but that doesn’t exist. There are, however, a solid handful of SEO tools that cover almost everything, making it easy to put your trust in one tool and then answer the little question marks with specialized outlier tools. 

The all-in-ones show overall SEO health. They start by crawling your site to perform a full SEO audit. The crawler looks for technical SEO issues like javascript errors, broken links, 404 pages, redirects, duplicates, bloated image file sizes, improper metadata (titles, meta descriptions, headers, canonicals, alt tags that are missing or too long or too short), and much, much more. 

Here are the SEO tools that get 90% of the job done and deserve first consideration:

1. Ahrefs Webmaster Tools (AWT)

Why is Ahrefs a favorite? It does everything right, that’s why. 

Its user interface and user experience are clean, comprehensive, and clickable. It covers the basics like site audit (SEO technical issues) and site explorer (backlinks and keyword ranking). But then, unlike many comprehensive SEO marketing tools, Ahrefs Webmaster Tools tells you how to fix each issue

It goes beyond the graphs of Google Search Console, giving page-level insight and things like SERP snapshots with competitive data. Itemized issues are ranked by importance (and color-coded) so you can click into every part of it and find actionable advice tips. Plus, it’s a completely free SEO tool.

2. Screaming Frog Spider Tool

An ugly workhorse, Screaming Frog’s spider tool is trusted across the internet, and it’s a free SEO tool up to a 500 URL crawl limit or paid without limits at an affordable $200 USD/year.

3. Semrush SEO Toolkit

If you’re already familiar with Semrush, you can’t go wrong with the industry-standard SEO Toolkit. Paid after a free trial, professional and powerful, but pricey at $120/month

4. Moz Pro

A long-time industry standard, Moz Pro is easy to use, and it packages with white-label features. Plus, the adorable handlebar moustache-famous Rand Fishkin helps you out with how-to videos and whiteboard Fridays. But, it has hard limits on its free stuff, and it costs more than comparable tools.

5. Google Search Console (GSC)

This is a must-have tool for search result stats, reports, issues, and performance monitoring in Google Search results. Associate your Google Analytics account to the Search Console for actionable insights—if you know how to read them. If you don’t, 👆 Ahrefs Wordmaster Tools is up there 👆.

6. Growthbar

Growthbar gets a crazy high 4.9/5 review on G2 with a 10/10 for ease of use and a 10/10 for support. Not a bad way to gain popularity as a relative newbie in the SEO toolbar game. The design is straightforward and clean, and Growthbar touts itself as the first end-to-end SEO tool to use OpenAI GPT-3 (the largest language model ever created). 

Used by thousands of companies (like Monday.com and Square), this one impresses with a free trial and monthly plan as low as $29/mo.

Growthbar has powerful insights in a simple interface

7. Raven by TapClicks All-in-one platform

Free for one website then affordable scaled plans, Raven is gaining traction in the all-in-one SEO marketplace.

8. SE Ranking

A no-fuss all-in-one SEO tool with a friendly interface, tons of social proof from high-falutin’ companies (like Mashable, Search Engine Journal, and Inc), and a great 5/5 rating on G2, which named SE Ranking one of the “top 100 fastest growing products of 2021.” 

This is a good option for small budget-friendly businesses at only $18 a month for up to 10 websites (and a two-week trial period). 

Something cool: get 60% off if you go for weekly rank checking instead of daily.

The why, what, and how of SEO tools

Optimization never ends—SEO will always require regular tweaks. SEO tools provide and track valuable data. Notifications tell you how healthy your website is so that Google keeps showing you the love to appear before customers who need you and want to pay you money to help them.

Why you need them

You need SEO tools because optimization is the only way you’ll outrank your competition, showing up on the first page of SERP like a sparkly diamond that gets click value. 

Everything is for that click. 

What you do with them

Spend money on the all-in-ones and tuck some free tools in your kit. Use them to optimize your content, the technical stuff under the page, your link strategy reaching off your pages, and your videos.

How you make more money

  1. Understand that every business today needs an online presence optimized for search engines (SEO).
  2. Create an SEO toolset from the comprehensive list above.
  3. Use those tools to optimize what’s not working so your customers see you more often than they see your competitors, click your stuff, and become customers.

If you don’t fix those red flashing SEO beacons, you don’t show up when people search for you. 

So fix them. 

This is a competition, and you’re in it to win it.

What’s next?

CRO comes after SEO. 

SEO gets prospects to your page, but CRO gets them in your funnel—hooray! You’ve got what you need to nail part one. Now see what you can do about part two, Conversion Rate Optimization, because that conversion funnel turns prospects into customers.
