14 Best SEO Tools to Supercharge Your Marketing


14 Best SEO Tools to Supercharge Your Marketing

Marketers are increasingly prioritizing SEO over other marketing tactics. According to HubSpot, 61% of marketers say improving SEO and growing their organic presence is their top inbound marketing priority. So if you’re not too big on SEO yet, it’s time to jump on the bandwagon like most of your competitors.

Having said that, the world of SEO is constantly evolving and ranking on page one of search engine result pages (SERPs) is easier said than done. It can be overwhelming to keep a track of all the algorithm changes from Google and stay on top of the current search trends.

Luckily, there are several tools out there that enable us to work smarter and faster with SEO.

To that end, we have created a list of 14 best SEO tools which you can use to boost your marketing efforts.

14 Best SEO Tools for Marketers

1. Semrush

(Use it to conduct site audits, spy on competition, and generate on-page SEO ideas)

Semrush is a must-have tool if you want to outrank your competition in search engines. Only a few tools offer features that SEMrush does for the price it charges.

With Semrush, you can conduct site audits to fix any errors, check out organic and PPC keywords your competition is ranking for, do a backlink audit for your site as well as your competitor’s site, and even receive ideas and recommendations to improve the existing content on your site.

It may seem like Semrush is trying to do one thing too many, but it does almost everything with perfection.

SEMrush Site Audit - Best SEO Tools (2018)

Is it free?

No, although there is a free version of Semrush which allows you to do 3 searches/day and offers a glimpse of the results.

If you want maximum value out of this tool, I suggest signing up for their monthly plan which starts from $119.95. If you’ve never tried this tool before, you can sign up for a free 1-month trial here (worth $119.95).

After 14 days, your Semrush account will be downgraded to the free version, limiting your searches and search results.

2. Google Analytics

(Use it for traffic stats and search insights)

You can also use this tool to unearth LSI keywords to boost your content’s SEO.

Keyword Tool

Is it free?

The basic version is free, but if you want a more advanced version (called Keyword Tool Pro), then you need to pay a monthly fee of $48.

My advise is to stick with the free version as it allows you to get 750+ keyword suggestions and there are no restrictions on the number of searches you can give in a day.

8. CoSchedule Headline Analyzer

(Use it to create snappy, click-worthy headlines)

Title tag, which is the headline to your article, is a critical on-page SEO component. Your article headline can make or break your article. A good headline boosts CTR, and thereby improves your site’s SEO. A poor headline, on the other hand, gets ignored.

As a result, you need to spend time crafting the perfect headline to your blog post.

CoSchedule’s Headline Analyzer analyses your blog post’s headline by assigning scores to its overall quality and rates its ability to result in social shares, increased traffic, and SEO value.

Headline Analyzer

Is it free? 

Yes! It’s one of the best free SEO tools on the market. The alternative to Headline Analyzer is Brian Dean’s YoRocket WordPress plugin for which you have to pay $29/month. That’s too much money for the same functionality and features offered by this free tool.

(Use it to check a site’s domain authority and page authority)

  1. SemRush is hands down a great sEO tool. I never used paid version but have been reading that they have great features. The problem with most SEO tools is that they are mostly paid. Free version is very limited. There are many free seo tools such as from link-assistant, its good and it has free version. No matter what seo tool one uses, if blog doesn’t have quality content then that blog isn’t going to rank good in any search engines. Bing is starting to pick up speed and has improved its algorithm but still hasn’t in parallel pace with Google. To get faster and better results in SERP’s, SEO tools can help your blog outrank your competitors in short period of time. Understanding your traffic is most important, you have to serve your their needs.

  2. This is a massive list of plugins. I found another tool which is also very good, SEOPROFILER. One can explore many things with a free account as well. Many thanks for sharing this guide, Sandeep.

    • Hey Vikas – That’s so nice to hear. 🙂 Thank you so much for your kind words.

      W.r.t traffic, just hang in there and keep creating great content on a regular basis. Follow the SEO basics and leverage social media channels until you improve your search rankings. And focus on creating relevant backlinks for your site through blogger outreach. You’ll eventually get there.

      Wish you all the best.
