For example, Keyword Planner shows monthly search volume estimates and assists in finding related long-tail variations of seed keywords. Even just leveraging Google Autocomplete provides loose keyword inspiration.
Additionally, free website crawl tools like Screaming Frog or basic rank trackers can help analyze how a site is currently targeting and ranking for core keywords. While rudimentary, these free offerings allow glimpses into essential questions like What terms drive my traffic? And what keywords present opportunities? Before paying for premium tools, utilize the free solutions to conduct initial keyword exploration and on-page optimization research.

What Are Some Must-Have Features To Look For In Free Seo Tools?
The most useful free SEO tools should provide insights into your current website optimization status and areas needing improvement. Core features to expect include site audits for technical and performance checks (e.g., indexing issues, broken links, page speed).
Keyword tracking capabilities to view search ranking positions over time, backlink analysis to inspect quality links pointing to your pages, and site crawler functionality to technically evaluate on-page content and HTML source code.
Free tools with customization options, easy-to-interpret reports, intuitive UIs, data exports, and integration or API connections have added appeal.
While not always present in free versions, also look for competitor analysis features, suggestion tools providing SEO recommendations, and annotation abilities to take notes on findings. Prioritizing these key capabilities will help extract the most SEO value from free tools.
Is There A Free Alternative To Ahrefs?
While Ahrefs is arguably the most powerful paid SEO tool for backlink analysis, site audits, and keyword research, there are a few free alternatives that provide useful basic functionality. The Moz Open Site Explorer allows you to analyze the backlinks pointing to any site, though with less in-depth metrics than Ahrefs.
Majestic SEO also offers a free backlink analysis tool. For site audits and crawler-based analysis, Screaming Frog offers a free basic version. Google’s suite of free tools – Keyword Planner, Search Console, and Analytics – can be utilized for DIY keyword and site analysis.
However, Ahrefs still provides vastly more advanced and comprehensive data, which is why it remains such a popular tool among professional SEO experts who need robust capabilities. The free alternatives serve for more casual analysis.
What Is A Site Audit, And Is It Free?
A site audit is an in-depth evaluation and analysis of a website, conducted to uncover opportunities for better search engine optimization (SEO) and user experience.
It involves technically crawling a site to identify issues negatively impacting performance, including broken links, metadata errors, accessibility problems, bad page speed, improper HTML markup, and issues preventing search engine crawling and indexing.
The audit generates reports summarizing the technical health of a site and provides recommendations to fix discovered flaws. It also examines competition benchmarking and evaluates traffic sources to provide additional SEO insights. Both free and paid tools are available to create site audits.
Free site audit tool options include Sitebulb, SEO Site Checkup, and Google’s suite of webmaster tools covering speed, mobile-friendliness, security, and indexing issues. They provide basic yet useful reports.
However, paid professional site audit software like Screaming Frog, Ahrefs, and DeepCrawl offer more comprehensive auditing capabilities for enterprise-level sites. Most WordPress site hosts also include free auditing limited to uptime and broken link monitoring. For bloggers and small sites, the free tools can sufficiently evaluate overall site health.
