110 Best SEO Resources That Are Totally Free

Whether you want to get started with SEO or want to achieve better results, here are the 110 best free SEO tools you should be using.

SEO (short for Search Engine Optimization) is the practice of tweaking your website to rank higher on search engines like Google. If your site isn't as high as you'd like, it's time to take a close look at your SEO strategy. 

The tried and true new SEO tools make it easier for site owners to find what they need to do to stay on top.

What are SEO tools?

SEO tools provide data and alerts on the overall health and success of your site. They help identify areas of opportunity and identify weaknesses or issues that may prevent you from ranking and gaining visibility in the SERPs. Just as the actual tools have a role to play, the same is true in SEO.

There are SEO tools that can help you:

• Analytics
• Keyword Research
• Links
• Local SEO
• Mobile SEO
• SEO on the page
• Research
• Rating check
• Site speed
• WordPress SEO

SEO tools are incredibly useful, but you need to understand how to use them to get the most out of them. 

There are even several toolkits that can help you in more than the areas just mentioned, giving you more of an overall view of SEO performance.

Do you need SEO tools?

Short answer: Yes.

Imagine that you are trying to build a table using only your hands. You won't get far will you? No. You will need tools - saws a measuring tape a drill and screwdrivers. 

Well if you want to create a website, you will only reach it with your own hands. You can build a website but without the tools you wouldn't know:

• How many visits do your web pages receive?
• Has traffic dropped significantly?
• If you have any HTML errors
• The number of links you have
• What keywords could you use to drive more visits?

And much more...
