Banyak orang berpikir SEO profesional butuh langganan Ahrefs atau SEMrush seharga ratusan dolar per bulan. Padahal sebagian besar pekerjaan SEO — riset keyword, audit teknikal, analisis backlink, cek kecepatan — bisa dilakukan dengan tools gratis yang kualitasnya tidak jauh beda.
1. Google Search Console
Ini adalah tools SEO paling penting yang wajib dipasang di setiap website. Gratis sepenuhnya dari Google. Kamu bisa melihat keyword apa yang membawa orang ke website-mu, halaman mana yang paling banyak diklik, error crawling, dan status indexing. Kalau hanya boleh pasang satu tools SEO, pasang ini. Daftar di search.google.com/search-console.
2. Google PageSpeed Insights
Kecepatan halaman adalah faktor ranking langsung. PageSpeed Insights menganalisis halaman URL manapun dan memberikan skor serta rekomendasi spesifik yang perlu diperbaiki — dari ukuran gambar, render-blocking JS, hingga server response time. Tersedia di pagespeed.web.dev.
3. Ahrefs Webmaster Tools
Versi gratis Ahrefs untuk website milikmu sendiri. Kamu bisa melihat backlink profile, broken link, keyword yang sudah kamu ranking, dan health score teknikal website. Tidak selengkap versi berbayar, tapi datanya dari database Ahrefs yang sangat besar dan akurat. Daftar di ahrefs.com/webmaster-tools.
4. Ubersuggest
Tools dari Neil Patel yang memberikan estimasi volume pencarian keyword, keyword suggestions, dan analisis kompetitor — gratis dengan batasan 3 pencarian per hari. Cukup untuk riset keyword harian tanpa bayar. Buka di neilpatel.com/ubersuggest.
5. AnswerThePublic
Tools ini menampilkan semua pertanyaan yang orang ketik di Google terkait satu topik — dalam bentuk visualisasi "who, what, why, how, when, where". Sangat berguna untuk menemukan ide artikel yang menjawab pertanyaan nyata yang dicari orang. Versi gratis tersedia di answerthepublic.com.
6. Screaming Frog SEO Spider
Versi gratis mengizinkan crawl hingga 500 URL. Screaming Frog mensimulasikan cara Google merayapi website-mu — menemukan broken link, duplicate content, missing meta tag, redirect chain, dan masalah teknikal lainnya. Wajib dipakai untuk audit SEO teknikal. Download di screamingfrog.co.uk/seo-spider.
7. Google Trends
Sering diabaikan, padahal sangat berguna. Google Trends menunjukkan apakah minat terhadap suatu topik sedang naik, stabil, atau turun — dan membandingkan beberapa keyword sekaligus. Berguna untuk memilih antara dua keyword yang volume-nya mirip tapi trennya berbeda. Buka di trends.google.com.
Semua tools di atas bisa dipakai bersamaan dan gratis. Mulai dari Google Search Console dan PageSpeed Insights — keduanya memberikan data paling langsung dari Google itu sendiri.
Many people think SEO professionals need Ahrefs or SEMrush subscriptions for hundreds of dollars per month. Even though most SEO work — keyword research, technical audits, backlink analysis, speed checks — can be done with free tools whose quality is not much different.
1. Google Search Console
This is the most important SEO tool that must be installed on every website. Completely free from Google. You can see what keywords bring people to your website, which pages are clicked the most, crawling errors, and indexing status. If you can only install one SEO tool, install this. Register at search.google.com/search-console.
2. Google PageSpeed Insights
Page speed is a direct ranking factor. PageSpeed Insights analyzes any URL page and provides specific scores and recommendations that need improvement — from image size, JS render-blocking, to server response time. Available at pagespeed.web.dev.
3. Ahrefs Webmaster Tools
Free version of Ahrefs for your own website. You can see profile backlinks, broken links, keywords that you have ranked, and website technical health scores. Not as complete as the paid version, but the data is from a very large and accurate Ahrefs database. Register at ahrefs.com/webmaster-tools.
4. Ubersuggest
Tools from Neil Patel that provide keyword search volume estimation, keyword suggestions, and competitor analysis — free with a limit of 3 searches per day. Enough for daily keyword research without paying. Go to neilpatel.com/ubersuggest.
5. AnswerThePublic
This tool shows all the questions people type in Google related to one topic — in the form of a visualization of "who, what, why, how, when, where". It is very useful to find article ideas that answer real questions people are looking for. The free version is available at answerthepublic.com.
6. Screaming Frog SEO Spider
The free version allows crawling up to 500 URLs. Screaming Frog simulates how Google crawls your website- finding broken links, duplicate content, missing meta tags, redirect chains, and other technical issues. Must be used for technical SEO audits. Download at screamingfrog.co.uk/seo-spider.
7. Google Trends
Often overlooked, even though it is very useful. Google Trends shows whether interest in a topic is rising, stable, or falling — and compares multiple keywords at once. It is useful to choose between two keywords whose volumesare similar but the trends are different. Go to trends.google.com.
All the tools above can be used at the same time and are free. Starting from Google Search Console and PageSpeed Insights-both provide the most direct data from Google itself.
