For those who are looking for free useful SEO tools, we tested and prepared a list of the 20 most useful SEO tools for free keyword search, back-link checking, and overall web page analysis. So if you have a tight budget, help with this list of free SEO tools. Of course, some of these tools have limits (signing up and getting their news 🙂 or a limited number of searches).

Keyword search

Moz defined keywords as ideas and topics that define what your content is about. In terms of SEO, they’re the words and phrases that searchers enter into search engines, also called “search queries.” If you boil everything on your page — all the images, video, copy, etc. — down to simple words and phrases, those are your primary keywords.

As a website owner and content creator, you want the keywords on your page to be relevant to what people are searching for so they have a better chance of finding your content among the results.

Back-link checking

Backlinks (inbound links, incoming links, inward links and inlinks) are hyperlinks that point towards your web site or blog from other domains all around the web. These links are one of the most important factors when it comes to search engine optimization (SEO) and will help your site achieve a higher rank on search engine result pages (SERP). Simply put, the more high-quality links you have pointing back to your site, the more popular search engines will deem your page, helping your site rank higher.

In the eyes of a search engine, the more inbound links a site has pointing to it, the more popular and valuable it must be to readers.

Key takeaway …

Inbound marketing is all about building trust. One of the steps for building that trust is by checking your on-page SEO regularly, so your page won’t have broken links and that it will have the right keywords people are looking for.

Google makes some of the best free SEO tools. My advice is to start there and then start to use paid tools. First, get to know what you really need, define your needs and then decide for the tools that meet those needs.
