Search Engine Optimization atau biasa dikenal dengan istilah SEO rasanya sudah begitu populer, bahkan dipelajari oleh sobat blogger. Hal ini sangat dimaklumi karena eksistensi seorang blogger di dunia maya salah satunya ditentukan oleh penguasaannya akan tekhnik / trik SEO. Bahkan ada pendapat yang menyatakan: menguasai SEO berarti 50% dunia online sudah digenggaman tangan.
Pengertian SEO (Search Engine Optimization)
Optimisasi mesin pencari (bahasa Inggris: Search Engine Optimization, biasa disingkat SEO) adalah serangkaian proses yang dilakukan secara sistematis yang bertujuan untuk meningkatkan volume dan kualitas trafik kunjungan melalui mesin pencari menuju situs web tertentu dengan memanfaatkan mekanisme kerja atau algoritma mesin pencari tersebut. Tujuan dari SEO adalah menempatkan sebuah situs web pada posisi teratas, atau setidaknya halaman pertama hasil pencarian berdasarkan kata kunci tertentu yang ditargetkan. Secara logis, situs web yang menempati posisi teratas pada hasil pencarian memiliki peluang lebih besar untuk mendapatkan pengunjung.
Sejalan dengan makin berkembangnya pemanfaatan jaringan internet sebagai media bisnis, kebutuhan atas SEO juga semakin meningkat. Berada pada posisi teratas hasil pencarian akan meningkatkan peluang sebuah perusahaan pemasaran berbasis web untuk mendapatkan pelanggan baru. Peluang ini dimanfaatkan sejumlah pihak untuk menawarkan jasa optimisasi mesin pencari bagi perusahaan-perusahaan yang memiliki basis usaha di internet.
Sejarah SEO (Search Engine Optimization)
Danny Sullivan berpendapat, istilah search engine optimization pertama kali digunakan pada 26 Juli tahun 1997 oleh sebuah pesan spam yang diposting di Usenet. Pada masa itu algoritma mesin pencari belum terlalu kompleks sehingga mudah dimanipulasi.
Versi awal algoritma pencarian didasarkan sepenuhnya pada informasi yang disediakan oleh webmaster melalui meta tag pada kode html situs web mereka. Meta tag menyediakan informasi tentang konten yang terkandung pada suatu halaman web dengan serangkaian katakunci (keyword). Sebagian webmaster melakukan manipulasi dengan cara menuliskan katakunci yang tidak sesuai dengan konten situs yang sesungguhnya, sehingga mesin pencari salah menempatkan dan memeringkat situs tersebut. Hal ini menyebabkan hasil pencarian menjadi tidak akurat dan menimbulkan kerugian baik bagi mesin pencari maupun bagi pengguna internet yang mengharapkan informasi yang relevan dan berkualitas.
Larry Page dan Sergey Brin, dua mahasiswa doktoral ilmu komputer Universitas Stanford, berusaha mengatasi permasalahan tersebut dengan membangun Backrub, sebuah mesin pencari sederhana yang mengandalkan perhitungan matematika untuk memeringkat halaman web. Algoritma tersebut, yang dinamakan PageRank, merupakan fungsi matematika yang kompleks berupa kombinasi antara perhitungan jumlah link yang mengarah pada suatu halaman web dengan analisis atas kualitas masing-masing link tersebut.
Berdasarkan prinsip kerja PageRank, secara umum bisa dikatakan bahwa halaman web yang memperoleh peringkat tinggi adalah halaman web yang banyak di-link oleh halaman web lain. Nilai PageRank juga akan semakin tinggi apabila halaman web yang mengarah kepadanya juga memiliki kualitas yang tinggi. Nilai sebuah link dari situs berkualitas tinggi seperti Yahoo! atau DMOZ dapat bernilai lebih tinggi daripada kombinasi nilai link dari seratus situs web berkualitas rendah.
Backrub hanyalah sebuah permulaan. Pada tahun 1998 Page dan Brin mendirikan Google yang merupakan versi tingkat lanjut dari Backrub. Dalam waktu singkat Google memperoleh reputasi dan kepercayaan dari publik pengguna internet karena berhasil menyajikan hasil pencarian yang berkualitas (tidak dimanipulasi), cepat, dan relevan. PageRank lantas menjadi standar baik bagi mesin pencari lain maupun bagi webmaster yang berusaha agar situs webnya memperoleh nilai PageRank setinggi mungkin sehingga menempati posisi tertinggi pada hasil pencarian.
