eMAG.ro a schimbat de curand un URL in site impreuna cu numele unei categorii. O miscare SEO ce mi-a adus aminte de un caz nefericit al altui magazin online penalizat pentru urmarirea aceluiasi scop final: imbunatatirea pozitiei in rezultatele la cautarea dupa termenii “notebook” si “laptop”.

Vechiul URL era “http://www.emag.ro/notebook”, titlul paginii fiind “Notebook”. Noul URL este “http://www.emag.ro/notebook_laptop” iar titlul “Notebook / Laptop”. Paginile de produs au ramas neschimbate, cu exceptia faptului ca s-a schimbat sectiunea din URL corespunzatoare categoriei.

Doua lucruri sunt tragicomice la aceasta “optimizare”.

Primul: categoria veche a disparut pur si simplu, la accesarea URL-ului se intoarce un header HTTP 404. O miscare extrem de neinspirata. Chiar angajati ai Google au recomandat folosirea 301 pentru mutarea si reindexarea rapida a noilor locatii. Dar raul e deja facut, continutul duplicat apare cel putin in rezultatele Google.

Si duplicatele URL-urilor de sectiuni:

In al doilea rand, URL-urile vechilor produse intorc un header HTTP 200, paginile afisandu-se fara nici o greata (1, 2).

Bineinteles, produsul poate fi accesat de motoarele de cautare prin ambele URL-uri si, la fel ca in cazul categoriilor, s-au indexat deja in dubluri. Diferenta e ca, spre deosebire de categorii care vor fi filtrate in timp din cauza header-ului 404, produsele genereaza un continut duplicat permanent si destul de insemnat. Lucru vazut cu ochi deloc buni de catre cel mai important motor de cautare. Iar unde nu-i cap, vai de picioare.
