9 Best OnPage SEO Tools Worth Trying (2019 edition)

9 Best OnPage SEO Tools Worth Trying (2019 edition)

Are you a search engine marketer on a shoestring budget?

Don’t worry, I was in the same spot until a few years back, with very little money to invest in the marketing of my personal projects.

Still, I was able to make those projects successful, thanks to some awesome onpage SEO tools available in the market.

I have covered 9 such free SEO tools that are either free or offer a freemium model. You can use these tools to set a rock-solid platform for your SEO campaigns.

9 Best Free OnPage SEO Tools for Budget Marketers 

1. Ubersuggest (for finding the right keyword)

Purpose: Keyword research
Pricing: Free

If you are a digital marketer on a low budget, UberSuggest is your go-to tool for keyword research.

UberSuggest provides you with the most important data around keywords: it’s search volume, search difficulty (SD) score, paid difficulty (PD) score and cost per click (CPC).

Here’s a video from Neil Patel showing how to use Uber Suggest.

You can also use UberSuggest to derive competitor intelligence around their most successful keywords and content assets.

In short, UberSuggest can let you kickstart your organic search campaign for free. I find this tool especially useful for beginners and mid-level marketers who may not be needing advanced/sophisticated keyword analysis offered by many paid tools.

Pro Tip: You should use UberSuggest to co-relate search volume to search difficulty score. This will help you identify interesting opportunities around potential target keywords for your organic campaigns. That’s enough meat for you to dig deep and explore ranking opportunities for that keyword.

2. Keywords Everywhere (for that Eureka moment)

Purpose: Keyword research
Pricing: Freemium [Update: From 1st Oct 2019, Keywords Everywhere has become a paid tool. 🙁 ]

Most of the time, you are searching the web for multiple keywords without realizing the potential of those keywords.

Keywords Everywhere come as a Chrome and Firefox browser extension and instantly shows you the volume for each keyword that you search for, right on the spot.

This tool can help you uncover many hidden opportunities and ensure you never miss out on the obvious ones.

Pro Tip: While using the KE tool, if you come across an intent based keyword with sufficiently high search volume, you should put this keyword in UberSuggest to know the Search Difficulty score.
A low SD score (anywhere below 30-35) indicates a very good SEO ranking opportunity.

3. Answer The Public (for finding specific content ideas)

Purpose: Content Idea generation tool
Pricing: Freemium

Once you have shortlisted a keyword, consider running it through AnswerThePublic.

This tool fetches related search queries from Google and Bing and categorizes them across how, when, what, where, etc.

Answer the Public_Content Idea generation tool

This can be a goldmine in terms of content planning since it tells you how users are searching the internet for a particular keyword. Equipped with this insight, you can create content exactly in the way your user is searching the internet.

Pro Tip: This tool is extremely helpful to generate super niche ideas. For e.g., if you put “best SEO tools” in this tool, you may get a search query on “best free onpage SEO tools”. That’s how you strike gold.

4. OnPage Champ (for competitor research)

Purpose: Competitor research and onpage SEO analysis
Pricing: Freemium

We have built OnPage Champ to solve a very common SEO problem: How to track onpage changes and their impact on SEO rankings?

Very often, you will find that you keep on making changes to your page without realizing what’s working for you and what’s not. OnPage Champ will remove all the guesswork and help you track your onpage SEO changes as well as relate them to rank fluctuations.

Another unique feature of OnPage Champ is that it helps you run a competitor on-page SEO analysis very quickly.

Previously, you have to manually visit top ranking URLs and see how the content elements are structured, and then dig out opportunities.

With OnPage Champ’s SERP Audit, you get this analysis, all in a single dashboard at just a click of a button. This can save you hours of research.

5. Yoast for WordPress (for onpage SEO optimization)

Purpose: Content optimization
Pricing: Free

Once you have written your content on the WordPress platform, you can use Yoast to key in a focus keyword and check how well the content is optimized.

Yoast SEO_OnPage Optimization plugin

Yoast immediately provides you with a list of recommendations to optimize your content for that focus keyword.

While a green signal by Yoast doesn’t guarantee a first-page rank, it is a good enough indicator that the basic on page SEO is in place.

Here’s an indepth video of features provided by the Yoast plugin.

Yoast is one of the best free SEO plugins to use but you can pay to unlock a few extra features as well as get dedicated support. Biggest disadvantage of using Yoast is that it still focuses on one keyword and shows no analysis on the usage of LSI keywords, which I think is a big miss.

Pro Tip: Not just content optimization, Yoast also gives you control across multiple on-site parameters like auto-generating XML sitemap, making a page no follow/no index, editing robots file, etc.

6. LSI Graph (to discover LSI keywords)

Purpose: LSI keyword research
Pricing: Freemium

The occurrence of LSI keywords is probably one of the most important ranking signals for Google. LSI keywords include those words/phrases that frequently appear together and are semantically related to each other.

It is an indication of how natural web content is.

Thanks to LSIGraph, you can see the list of LSI keywords for your focus keyword and can incorporate them as part of your content.

Under the freemium plan, you get to know the LSI keywords but not their search volume, which I think is still fine since you have done the keyword research around the primary keyword.

Pro Tip: You are allowed only 5 searches per day in the free plan, so use your quota wisely.

7. TinyPNG (for image compression)

Purpose: Improving page load time
Pricing: Freemium

Before you are ready to hit the publish button on your latest content piece, have all your PNG and JPEG images processed by TinyPNG.

It does a smart compression of an image without any significant loss, thereby resulting in faster page loads.

TinyPNG_Compress page images

You just need to drag and drop the files on the web page. TinyPNG also tells you the percentage of compression done for each image.

In its free plan, TinyPNG allows you to compress up to 20 images in a single drag and drop, with a size limit of 5 MB for each image.

However, there is no limit to the number of images you can compress via multiple drag and drops.

8. GTMetrix (to discover page speed improvements)

Purpose: Improving page load time
Pricing: Free

GTMetrix should be your go-to tool after you have made any major change on your website.

It not just shows you the page load speed but also offers suggestions and improvement areas.

GTMetrix_improve page load speed

It uses a combination of Google Page Speed Insights and YSlow Insights to churn out scores and speed improvement suggestions which are very practical and easy to follow.

You get a host of features and recommendations under their free plan and I can guarantee you would not need their paid service pretty soon.

9. Google Search Console (for everything SEO)

Purpose: SEO performance
Pricing: Free

So you have written an awesome content piece and have hit the publish button.

Now use the Google Search Console tool to track how Google bot interacts with this content piece. Using this tool, you can see the performance of each page in terms of webiste ranking, keyword impressions and organic clicks generated.
