You do not need to spend thousands of rupees on premium SEO software to run an effective SEO campaign — especially when you are just starting out. There are powerful, completely free SEO tools that can handle most of what small businesses need.

As a affordable SEO agency in Mumbai, DigitalBacklinger uses a combination of free and premium tools for our 150+ clients. Here are the best free ones available in 2026.

Google's Free SEO Tools (Most Important)

1. Google Search Console

Google Search Console (GSC) is the most important SEO tool available — and it is completely free. It is provided directly by Google and shows you exactly how Google sees your website.

What you can do with GSC:

• See which keywords bring traffic to your site and at what positions
• Monitor your click-through rate (CTR) for different queries
• Identify crawl errors, indexing issues, and security problems
• Submit your sitemap.xml for faster indexing
• See which pages are indexed and which are not
• Monitor Core Web Vitals performance
• Receive manual action notifications

If you only use one SEO tool, make it Google Search Console. Every website should have it installed.

2. Google Analytics 4 (GA4)

Google Analytics 4 tracks all traffic to your website — including how much comes from organic search, how users behave on your site, which pages are most popular, and what percentage of visitors convert.

For SEO, GA4 helps you understand whether your rankings are translating into actual traffic and conversions — the ultimate measure of SEO success. Always connect GA4 with GSC for the most complete picture.

3. Google Business Profile

If you are a local business, your Google Business Profile is a free tool that controls how you appear on Google Maps and local search. We cover GBP optimisation in detail in our GMB SEO guide.

4. Google PageSpeed Insights

PageSpeed Insights analyses your website's speed and Core Web Vitals on both desktop and mobile. It provides a score from 0-100 and detailed recommendations to improve your site's loading performance — which is a direct ranking signal in 2026.

Free Keyword Research Tools

5. Google Keyword Planner

Free with a Google Ads account (you do not need to run ads). Shows search volumes, competition levels, and related keyword suggestions. Excellent for finding long-tail keywords with decent traffic and lower competition.

6. Ubersuggest (Free Tier)

Neil Patel's Ubersuggest offers a free tier with keyword research, search volume data, keyword difficulty scores, and basic competitor analysis. The free version allows a limited number of daily searches — enough for small businesses just getting started with their SEO strategy.

7. AnswerThePublic (Free Searches)

AnswerThePublic maps out all the questions people ask around a keyword — visualising "who," "what," "why," "how," and "which" variations. It is incredibly useful for finding content ideas and long-tail question keywords that are easy to rank for.

8. Google Trends

Google Trends is completely free and shows you the relative search interest in keywords over time. Useful for identifying seasonal trends, understanding whether a topic is growing or declining, and comparing multiple keywords.

Free Backlink Analysis Tools

9. Ahrefs Free Backlink Checker

Ahrefs offers a free backlink checker that shows the top 100 backlinks to any website, the Domain Rating, and the number of referring domains. Use it to analyse your own backlink profile and to spy on competitor backlinks — identifying opportunities for your own link building campaign.

10. Moz Link Explorer (Free Searches)

Moz Link Explorer offers a limited number of free searches per month. It shows Domain Authority, Page Authority, spam score, and the top linking domains to any website. Useful for quickly vetting the quality of a website before requesting a backlink from it.

Free Technical SEO Tools

11. Screaming Frog (Free up to 500 URLs)

Screaming Frog SEO Spider crawls your website like Google does — identifying broken links, missing meta tags, duplicate content, redirect chains, and dozens of other technical issues. The free version crawls up to 500 pages, which is enough for most small business websites.

12. Schema Markup Generator

Tools like TechnicalSEO.com's Schema Generator are completely free and help you create schema markup (structured data) for your website without coding knowledge. Schema helps Google display rich snippets in search results — improving click-through rates.

Free Content & On-Page SEO Tools

13. Yoast SEO (Free WordPress Plugin)

For WordPress websites, Yoast SEO is the most popular free plugin for on-page optimisation. It analyses your content for keyword usage, readability, meta tags, internal linking, and more — giving you a simple traffic-light system to improve each page.

14. Hemingway Editor

Hemingway Editor is a free tool that analyses the readability of your content. Clear, readable content performs better in SEO — Google's algorithms increasingly favour content that is easy for humans to understand. Aim for a Flesch Reading Ease score appropriate to your audience.

Free Local SEO Tools

15. Google My Business Insights

Built into your Google Business Profile, GBP Insights shows you how many people found your business through Google Search and Maps, what queries they used, how many called you, and how many requested directions. This is your free dashboard for tracking local SEO performance.
