110 Top SEO Tools That Are 100% Free
7 months ago on August 08, 2023
SEO (short for search engine optimization) is the practice of tweaking your website so that it ranks higher on search engines like Google.
If your site isn’t ranking as high as you’d like it to, it’s time to take a good look at your SEO strategy.
Tried and true, as well as new, SEO tools make it easier for site owners to find what they need to do in order to stay on top.
What Are SEO Tools?
SEO tools provide data and alerts about the overall health and success of your website.
They help uncover areas of opportunity and identify weaknesses or issues that may prevent you from ranking and earning visibility in the SERPs.
Just as actual tools each have a specific role, the same is true in SEO.
There are SEO tools that can help you with:
- Keyword Research.
- Local SEO.
- Mobile SEO.
- On-page SEO.
- Rank Checking.
- 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 a few toolsets that can help you in more than the areas we just mentioned, giving you more of an all-at-once glance at your SEO performance.
Do You Need SEO Tools?
The short answer: Yes.
Imagine trying to build a table using only your hands.
You wouldn’t get very far, would you?
You will need tools – saws, a measuring tape, a drill, and screwdrivers, to name a few.
Well, if you want to build a website, you’ll only get so far with your hands.
You can build a website, but without tools, you wouldn’t know:
- How many visits your webpages are getting.
- Whether traffic has dropped significantly.
- If you have any HTML errors.
- The number of links you have.
- What keywords you could be using to attract more visits.
And so much more.
