If there’s one thing about SEO most consultants, freelancers, agency owners (and clients) can agree on, it’s this:

It can take a lot of time to see success with an SEO strategy.

That’s why there are so many technical SEO tools, link building guides and blog posts about keyword research to help make the various SEO tasks much easier to manage.

On-page SEO is no different.

It is a vital part of success to any SEO campaign, and there are several elements you need to manage—checking meta tags, optimizing headings, writing content for SEO, and more.

This article is a quick rundown of the best on-page SEO tools, what they are, why they’re important, and how to use them to get more search traffic.

But first:

What Is On-Page SEO and Off Page SEO?

First, it is important to understand the difference between on- and off-page SEO.

Anything that is “on-page” refers to the SEO factors that occur on your website at the page-level. You have direct control over every SEO element that is on your own pages.

Off-page SEO refers to SEO elements that occur beyond your website, such as backlinks, social media, and so on. You don’t always have full control over off-page elements.

While there are SEO tools for both, this guide will only cover on-page optimization tools.

Why Does On-Page SEO Matter?

On-page SEO is important because it is how you control how search engines and users see the content on your web pages.

It affects how your pages appear in SERPs, it helps search engines understand your pages when it crawls them, and so on.

You can think of on-page SEO as being the introductory sales pitch from your business to Google and your audience. Having a website that is highly optimized helps you rank better for target keywords, increase traffic, and earn more backlinks.

What Are The Most Important Parts of On-Page SEO?

While there are several important elements for on-page SEO, there are a few that are more important than others. The best on-page SEO tools will be what helps you optimize your pages for these:

  • Keywords: including keywords in the content, meta tags, heading tags, etc
  • Content: writing high quality and relevant content for target and semantic keywords
  • Internal links: adding links to other relevant pages on your website
  • Page speed: having a page that loads quickly
  • Mobile friendliness: having a page that looks good and is fully functional on phones

If a tool also helps you with less important factors, you can consider that a bonus. But if you only have so much money to spend on tools, always pick the ones that help you in these areas.
