How to choose SEO tools
Google Search Console costs $0 per month and monitors your site issues directly. Frase costs $38 per month for its Starter plan and guides your writing. If you only need to fix technical site errors, start with Google Search Console. If you need immediate writing help, pick Frase.
The guide below helps you choose between Ubersuggest and Serpstat for Keyword Research and SEO Audit tasks. It also shows when Moz fits your budget better than other options.
Free site checks versus link scans
Google Search Console costs $0 per month and shows direct issue alerts for your site. Screaming Frog SEO Spider offers a free plan that scans up to 500 URLs per crawl. If you run a regular website and want ongoing error alerts without paying, pick Google Search Console. If you need to trace broken links across a smaller catalog under 500 pages, pick Screaming Frog SEO Spider.
Finding keywords on a budget
Ubersuggest provides a free plan at $0 per month along with lifetime payment options. Serpstat charges $50 per month on its Individual plan and checks search results across 230+ regional Google databases, showing what ranks in specific countries. If you need basic word suggestions without recurring charges, pick Ubersuggest. If you manage client work across multiple regional markets, pay for Serpstat.
Content creation versus link research
Frase costs $38 per month for its Starter plan and focuses on writing assistance. Moz starts at $20 to $75 per month on its Starter plan; it tracks domain authority, which scores how likely your pages are to rank, and checks site crawl health to find broken links and errors. If you need immediate guidance while drafting articles, pick Frase. If you need to inspect competitor links and fix page errors, pick Moz.
