We built this page as a one-stop resource.
When it comes to free SEO tools, we’d rather have one bookmark than many. This page was previously located off our domain, but we thought it might be helpful to other SEOs. We’re not trying to post the biggest count of free online tools, but the best SEO tools.
Content & Keywords
- Google AdWords Keyword Planner – Google’s own keyword research tool, the Keyword Planner was developed to help paid search advertisers, but is also used routinely by SEO’s. If you have an active Adwords account, your data will be more robust.
- Google Insights – Check out when a keyword is most searched. Helpful for choosing keywords for seasonal campaigns.
- Infinite Suggest – this is a great tool from RankTank that helps find keywords quickly and inspire content.
- Answer The Public is a very light, quick question discovery tool. Pick your subject (keyword) and language, and go. The questions provided might serve as possible topics or long-tail queries.
- SEMrush – we rely on this tool for some good competitive research and great keyword research..
- KeywordTool.io – unique name right? This tool takes your base term and appends/enhances it with letters and phrases, resulting in many more suggestions.
- Keyword Opportunity Finder – provides you with a whole lot of keyword suggestions and allows you to, at a glance, see which would be easier to rank for based on competition. It also crawls the top 10 results for any given keyword to see if the pages were optimized for that keyword.
- Alchemy API – Find out what entities, topics, and keywords represent a page.
- Rank Ranger – Stellar rank tracking tool with some free features. We use them . Daily SERP tracking, local rank tracking, whitelabel PDF reports. Integration with Analytics, Majestic, ahrefs, and Moz. Tons of features.
- Microsite Masters – For free you can get daily rankings (and trending) on 10 keywords.
- XML-Sitemaps.com – Great for a site with less than 500 pages. If you have a larger site, you could pay to get more than 500 pages.
- Screaming Frog Sitemap Generator – allows you to generate XML Sitemaps (& Image Sitemaps) for any website, to submit to Google or other search engines.
Social Media Tools
- Shared Count – Enter a URL, get the Facebook, +1, Twitter, LinkedIn, Digg, and Buzz social metrics.
- Buffer – Buffer helps you organize your publishing schedule in platforms like Twitter, Facebook, Instagram, and more.
- Open Link Profiler – A solid entry, totally free. We’re very much liking this one!
- Linkody – Free backlink checker using Ahrefs data.
- Open Site Explorer – Get some data for free, or pay for the full spectrum.
- Majestic – Another like above, usually with some different data.
- Ahrefs – Yet another like above. Really great detail, and one of our favorites. We definitely recommend using all three for a bigger picture of your backlink portfolio.
- Disavow Backlinks Wizard – free desktop app that allows you to view each linking page and judge for yourself if it’s spam or not.
- Google Analytics – The hero of free analytics. Some interpolated data, but a pretty robust interface. Segmentation and goal funnels are available. You can’t correlate as deeply as something like Omniture (arguably better suited for enterprise sites), but for SEO and marketing, this will likely serve the purpose just fine.
- Woopra – Real time analytics. Provides a nice view into live queries and active pages. Plus it’s just fun to watch your visitors navigate your site. The pay version gives you filters and navigation path. For certain strategies, I hang out here more than GA. It’s great ‘in your face’ insight.
- Social Crawlytics – Get insights on all your site pages, and the most popular shares across the big social platforms. This showed me that I’m a bigger deal on Linkedin than on Twitter, which I didn’t know. Cool tool.
- DD Whois – When you’re looking for a domain, this is a quick iPhone friendly way to check for availability.
- Screaming Frog – Desktop program with a 500 URL crawl limit in the free version which spiders websites links, images, CSS, script and apps from an SEO perspective.
- GA Checker – spiders a site to find pages containing, or not containing, various GA code versions, GTM, AdWords, and DoubleClick tags.
- URI Valet – Scans a page for headers, tag content, content density, objects, external links, and speed.
- WooRank – Also scans a page for a quick summary of traffic estimations, site rank, popular pages, tags, and more. (Thanks Brian)

Comparison / Competitive Tools
- The Wayback Machine – Archive.org has snapshots of decades old websites. Nice if you have a need to see competitor changes, or have a client who’s content or URLs suddenly disappeared.
- SEMrush – You only get a little for free here (you pay to unlock the full beast), but this tool is great for giving you insight into what your competitors are bidding and organically ranking for. This is one of our favorites.
- Google Analytics URL Builder – Simple tool to help you whip up tracking parameters for your URLs.
SERP Fluctuation Monitors
