New Tools I’ve tried and liked in the last 3 months

1. QuuuPromote

Use QuuuPromote to get your social signals through the roof. You essentially create a promotion, select a link to promote, create the message to be shared on FB/Linkedin/Twitter and hit send!

2. Clearscope

Clearscope empowers your content team to create near-perfect SEO articles.

You can run a report on a keyword like “marketing tools” and it will give you a list of related keywords that you can use, alongside the number of times that keyword appeared on the top 30 blog posts.

3. Keyword Clustering by ContentDistribution

Keyword clustering is a way to group similar keywords and understand the volume that the group receives.

For instance, in the past if you were targeting keywords like {dog breeds, types of dogs and list of dog families} you might have needed to write 3 articles since the keyword research might have showed them as not closely related.

Now with keyword clustering you can create one super keyword group (cluster) and understand that you only need 1 article to rank for all those 3 keywords.

This is a service offered by ContentDistribution.

Now let’s review all the best SEO tools out there.

Best SEO Linking Building Tools

1. AuthoritySpy

With AuthoritySpy, you can very easily find the top bloggers, influencers and thought leaders in your space. In the dashboard, you can quickly find their contact info such as Twitter, Facebook or public email and save a lot of time when doing outreach to build those precious backlinks.

When you find someone that you would like to reach out, I recommend using this outreach strategy to get more answers.

2. Google Gmail Mail Merge

If you plan to reach out to hundreds or thousands of people, then I suggest you install this Mail Merge Chrome Extension which will allow you to write personalized emails and also include attachments.

3. Broken Link Finder

If you really on finding broken links and asking webmasters to link to your content instead of a 404 page, then this tools is for you.

With Broken Link Finder, you can feed it the keywords that you are looking for and then the tool will search the web for any broken link that matches your criteria. Even better, it can rank results by the amount of sites that point to that broken link = $$$.   

4. HARO (Help a Reporter Out)

By far one of my favorite and most fun ways to build links.

Help A Reporter Out is a tool that essentially sends you PR opportunities right to your inbox. Reporters create queries, such as “looking to hear from a business owner that struggled their first year”, and gather a few words from you to create a post that contains a link to your site.

With HARO, you are not only you are getting a backlink for free but you are also establishing yourself as an authority in your niche.

SEO Bonus: Getting yourself linked on Forbes, Mashable, Techcrunch and other authority sites will give you a very powerful backlink that will also increase the domain authority of your site.

5. Broken Link Check

I like to use this tool to check for any broken links that I might have on my own site. That way I can quickly clean them up or potential even advertise those broken links to people in my network that might want to write some content about it.

Don’t want to waste all your life doing SEO? Hire me and I’ll gladly take over your project (big or small). Contact me here.

Best technical SEO tools and plugins

1. Yoast SEO WordPress Plugin

By far one of my favorite plugins, Yoast SEO does all I need when it comes to analyzing my site’s internal SEO.

From Yoast, you can update the title and description meta tags, see the keyword density and optimize your posts for social.

2. Google’s Search Console

With the search console, you can see any crawl errors that the Google bot might have encountered, see how your site looks to Google and more.

Moreover, you can look at the Search Analytics and find useful information such as CTR, impressions and clicks. Here what I like to do is find keywords that I am getting a ton of impressions for but not enough click and target those keywords by extending my blog posts to include more information.

One of my favorite tools is Fetch as Google.

3. SEO Site Checkup

A quick and dirty service to check on many potential errors on your site such as HTML compressions, H1/H2 tags, presence of robots.txt, and more.

I like to use the SEO Site Checkup to provide easy-to-understand white labeled reports to my clients.

4. Google Mobile Friendly Test

By now, you should now that Google has been seriously penalizing sites that are not mobile friendly.

You can use their own tool to test if your site is mobile friendly. Very handy.

5. AMP for WP Plugin

This is a very powerful way to rank high on Google in no time.

Google created the AMP (Accelerated Mobile Pages) project to ensure that sites load blazingly fast without having to wait for any heavy Javascript or other scripts.

If you are not a coder, you can quickly embed that functionality to your site with the AMP for WP plugin.

Fun fact: If you are reading my site on mobile, then you are seeing the AMP version right now.

6. Pingdom Website Speed Test

Site load speed is one of the SEO factors Google uses to rank your site.

With Pingdom’s site speed test you can see which files need to be optimized, minified or deleted from your site.

Other speed tools:

• web.dev
• Think With Google

Screaming Frog SEO

Who would have thought a squeaky reptile would be so helpful?

With Screaming Frog you can do pretty much all the on-site SEO analysis that you want. With the Log File Analyzer you can see the crawler’s log and understand how the bots interact with your site and in what frequency.

Best part? It also integrates with Google Analytics, Ahrefs, Google Search Console.

8. SEObility

With SEObility you can see how many pages deep your content is.

(i.e. if you have a homepage that has a link to “SEO guides” and then in that page you have a blog post titled “SEO tips for 2020”. That piece of content is 2 pages deep.)

Content that is several pages deep is very hard to index. With this tool, you can see which pages are hard to reach and bring those links closer to your homepage by means of internally linking it to other pages.

Best SEO tools for Keyword Research

Here are the best tools to do keyword research.

1. Google Keyword Planner

Perhaps the most well-known tool out there. With this Keyword Planner tool, you can not only see how much traffic a particular set of keywords generates but also how much is that traffic worth.

If one of your monetization strategies is Adsense, then you can target the highest CPC keywords in your niche.

2. Answer the public

“How to do SEO”

“What is Search Engine Optimization”

“How to write a novel”

These are different queries that people type on Google every day.

With Answer the Public you can quickly see which questions people are asking and craft blog posts to answer those queries.

If you write a perfect blog post that answer that question in depth, you might even win the Featured Snippet section on Google, driving you most of the traffic for that query. Considering that only about 12% of the results have a Featured Snippet, you will most likely win that spot.

3. Ahref’s Site Competitor Analysis and Keyword Explorer

What better place to find keywords than to see what your competitors are ranking for. Simply type a site you want to analyze and it will quickly return the keywords they are targeting.

Also you can use their Keywords Explorer to seed millions of keywords and also get their KD (Keyword Difficulty).

Ahrefs is the main tool I use for 99% of my tasks. I love it.

4. Google Location Changer

With Local SEO becoming a major part of how Google renders their results, it is imperative that you rank well for the community that you serve.

With the location changer, you can see how the SERPs (Search Engine Result Pages) look for a particular city. Quite useful.

5. Google Trends

Google Trends is essential for your site if you want to write content that will continue to drive traffic later on.  

You don’t want to write about fidget spinners after all the hype has died down, for instance.

6. SEMRush

Can’t have a list without SEMRush.

Very similar to Ahrefs, SEMRush allows you to analyze your competitor very well. You can hop in and see their most visited pages and know which keywords are driving the most traffic to them.

Then you can create content that is better optimized and more valuable and take over their Google ranking. #savage

7. What’s My SERP

I used to love KeywordsEverywhere but since they went paid, I no longer use it.

Luckily, WhatsMySERP is free.

WMS shows you related keywords when you do a Google search, and also shows you their volume, CPC and difficulty.

Very handy because it can give you great ideas as you go through your normal Google searching.

If you have a paid Ahrefs account, you can use the Ahrefs toolbar to get keyword data on your daily Google searches.

Some more tools that the experts recommend currently

1. SpyFu

If you have a need for a more complex SEO tool, SpyFu is the right choice for you. 

It can be quite confusing for people that are not experienced with SEO so it’s not recommended for novices. SpyFu offers a big selection of keyword search and management tools, interactive reporting, PPC/CPC, backlink tracing, and much more.

2. Moz Pro

Moz Pro is an end-to-end SEO solution that covers crawling, keyword management, and website optimization. The metrics that Moz Pro uses are so advanced that are an industry standard for many marketers. It is a very powerful and dynamic tool, and the only downside is perhaps it’s user experience. Since it’s a very complex tool, it can be confusing for novices.

3. KWFinder

KWFinder is a tool that doesn’t offer a big array of functionalities connected to SEO like SpyFu and Moz Pro. However, the functions that it has are top-notch. And it comes with a pretty low price. Its specialty is ad hoc keyword search, detailed related keyword suggestions, SERP-specific keywords, rank tracking, etc. If you need only a keyword focused SEO tool- this one is the right for you.

4. Ubersuggest

Ubersuggest is a SEO tool that is currently free and hence quite limited. It is mostly about identifying keywords to target, and discovering related keywords. Basically it is a tool like Ahrefs, SEMRush, MOZ, etc. but with limited functionalities. Because of that it is suitable for freelancers or people that don’t have a lot of budget to spend on SEO tools.

Bottom line

So there you have it, those are the tools that I use on my everyday SEO adventures.

Hope you found this list very helpful and that all these tools help you save valuable hours of work. If you did, share this post via Twitter or Facebook 🙂

How SEO tools (overview) works in AI search engines (ChatGPT, Perplexity, Google AI Overviews, Claude)

The 2026 SEO tool stack has three layers: classic SEO (Ahrefs/SEMrush/SE Ranking for keyword research, ranking, backlinks), content optimization (Surfer/Clearscope for on-page guidance), and AI-search visibility (Profound/Athena for AI-engine citation tracking). Each layer addresses different decisions; combining all three is now standard for serious SEO programs.

Budget allocation tip in 2026: most teams underspend on the AI-search visibility layer relative to its strategic importance. A starter setup of Ahrefs + Profound covers 80% of decisions; adding Surfer or Clearscope helps with content production. Stacking three classic SEO tools is rarely worth it — pick one and add the AI-search tool instead.

The 4-block GEO scaffold for SEO tools (overview)

1. Lead with a TL;DR. 2-4 sentences at the top of the post that answer the head query directly. AI Overviews and Perplexity preferentially cite this block.
2. Add a numbered step-by-step section. Generative engines extract clean ordered lists into their answers more reliably than prose.
3. Close with an FAQ. Use the literal phrasing of questions people actually ask in your niche; mark up with FAQPage schema.
4. Cite primary sources. Link to Google’s own AI Overviews documentation, OpenAI’s structured-data guidance, and Anthropic’s content-quality posts. LLMs trust pages that cite the model providers themselves.

FAQ — SEO tools (overview) in the AI search era

Do I still need a classic SEO tool in 2026, or can I get by with AI-search tools alone?

You still need a classic SEO tool for keyword research, ranking, and backlinks. AI-search tools are additive; they don’t replace the classic layer yet.

Which AI-search tool should I start with in 2026?

Profound for AI-engine citation tracking is the most-mature option. Athena is competitive. Both will show similar core data; pick based on UI preference and pricing for your tier.

Are free AI-search tools worth using?

Free tools in this space are limited as of 2026 — manual sampling is more reliable than the free options. Budget for at least one paid AI-search tool if you’re serious about GEO.
