What Nigerians Actually Search For

We pulled Google Trends data for every SEO-related search in Nigeria from 2021 to 2026. This is the data nobody else is showing you.

Plagiarism checker is #1with an interest score of 100. Not “seo tools.” Not “keyword planner.” Plagiarism checking. Nigerian content creators are obsessed with content uniqueness - and for good reason. Duplicate content from supplier websites tanks your Google rankings.

Here is what surprised us. Kwara state has the highest interest in “seo checker” (score 100). Osun is second at 71. Oyo is third at 53. Lagos? Just 18. FCT? 17.

Businesses outside Lagos are actively searching for SEO tools - and the market is underserved. If you run a business in Ilorin, Osogbo, or Ibadan, your competitors are looking for ways to rank on Google right now.

• + Load times on Airtel 3G in Ikeja and MTN 4G in Wuse, Abuja
• + Accuracy against 5 known Nigerian website issues

This is the only free SEO tool built specifically for Nigerian businesses. We built it because nothing else tested on Nigerian networks or understood Maps 3-Pack signals.

• + 50+ ranking factors scored in 60 seconds
• + Maps 3-Pack predictor - probability of ranking in Google Maps top 3
• + JSON-LD schema generator - CAC-compliant with Nigerian addresses
• + Built-in plagiarism checker and dead link checker
• + Page speed tested on real Nigerian 3G/4G

2. Google PageSpeed Insights

URL: pagespeed.web.dev

• + Best for Core Web Vitals - the metrics Google uses for ranking
• + Tests on real devices (Chrome UX Report data)
• + Completely free, unlimited, no login

• - No Maps 3-Pack check
• - No JSON-LD schema generation
• - Recommendations assume European/American hosting

Our test:Scored our test site 91/100 on mobile. Load time on MTN 4G in Wuse, Abuja: 2.1 seconds. Flagged “reduce server response time” without mentioning the server is in South Africa - common for .ng sites.

Use this if: You want to check Core Web Vitals. Run it monthly. But pair it with a tool that checks Maps and schema.

3. SmallSEOTools

URL: smallseotools.com

• + Best plagiarism checker - matches the #1 Nigerian search query (score 100)
• + 50+ free tools in one platform
• + No registration for basic checks

• - Free tier limited to 1,000 words per check
• - Heavy ads slow down on 3G

Our test: Plagiarism check for 500 words completed in 8.3 seconds on Airtel 3G. Page took 4.2 seconds to load due to ad scripts.

Use this if: You need to check content uniqueness before publishing. The plagiarism checker is genuinely useful.

4. Seobility

URL: seobility.net

• + Best free technical audit - crawlability, meta tags, headings, structured data
• + Partial schema validation
• + Clean interface with actionable recommendations

• - Free tier: 1 domain, 1,000 pages
• - No Nigerian network testing

Our test: Audit completed in 12.4 seconds on 3G. Found 3 broken links and 2 missing meta descriptions. But suggested moving to a European server - irrelevant for .ng sites.

Use this if:You want a deep technical audit and don't mind the 1-domain limit.

5. Ubersuggest

URL: neilpatel.com/ubersuggest

• + Best for keyword ideas - search volume, difficulty, content suggestions
• + Competitor analysis shows what keywords they rank for

• - 3 searches per day on free tier
• - Nigeria keyword data less accurate than US/UK

Our test:Searched “plumber Lagos” - showed 1,300 monthly searches (Google Keyword Planner shows 880). Load time on MTN 4G: 2.9 seconds.

Use this if: You need keyword research. Use your 3 free searches wisely - check your top 3 money keywords.

6. Ahrefs Free Backlink Checker

URL: ahrefs.com/backlink-checker

• + Best backlink data - referring domains, anchor text, domain rating
• + Shows top 100 backlinks for any domain

• - Very limited free tier - no keywords, no audit, no rank tracking
• - Nigerian domains have fewer indexed backlinks

Our test: Checked a popular Lagos restaurant - Ahrefs found 47 referring domains. Free tier showed 15. Useful for benchmarking competitors.

Use this if: You want to understand your backlink profile or spy on competitors.

7. Neil Patel SEO Analyzer

URL: neilpatel.com/seo-analyzer

• + Clean interface - easy for beginners
• + Checks on-page SEO, content length, keyword usage
• + Unlimited free searches

• - Generic recommendations - “add more content” without specifics
• - No Maps, schema, or Nigerian network checks

Our test: Scored 68/100. Recommendations: write more, add internal links, improve page speed. Accurate but not specific enough to act on.

Use this if: You want a quick, free snapshot. Not detailed enough for serious optimization.

The 5 Things Every Nigerian Website Must Check

Regardless of which tool you use:

Paid Tools Worth Considering

Free tools cover 80% of what most Nigerian businesses need. But if you are ready to invest in SEO, here are the paid tools that are actually worth the money:

My advice: Start with free tools. Upgrade only when your business can afford it and you have someone who will actually use the tool.

Why Free Tools Matter for Nigerian SMEs

Most Nigerian businesses cannot afford $99/month for Ahrefs or SEMrush. A small business in Ilorin or Enugu is not going to pay N150,000/month for an SEO tool when they are still figuring out how to get customers.

Free tools level the playing field. A solo entrepreneur with SEO Checker Nigeria and Google PageSpeed Insights can audit their website better than a business paying for expensive tools but never using them.
