From today onwards I am going to apply these rules to fix issues with SEO.
Magento admin / System / configuration / General / Web / Auto-redirect to Base URL / Yes (301 Moved Permanently)
Also, add robots.txt file with below content.
User-agent: * Disallow: /*.css$ Disallow: /*.js$ Disallow: /*.php$ Disallow: /*?SID= Disallow: /404/ Disallow: /app/ Disallow: /catalog/category/view/ Disallow: /catalog/product/view/ Disallow: /catalog/product_compare/ Disallow: /catalogsearch/ Disallow: /cgi-bin/ Disallow: /checkout/ Disallow: /control/ Disallow: /cron.php Disallow: /cron.sh Disallow: /customer/ Disallow: /customize/ Disallow: /downloader/ Disallow: /error_log Disallow: /errors/ Disallow: /includes/ Disallow: /index.php/ Disallow: /install.php Disallow: /js/ Disallow: /lib/ Disallow: /LICENSE.html Disallow: /LICENSE.txt Disallow: /LICENSE_AFL.txt Disallow: /magento/ Disallow: /newsletter/ Disallow: /pkginfo/ Disallow: /poll/ Disallow: /report/ Disallow: /review/ Disallow: /scripts/ Disallow: /sendfriend/ Disallow: /shell/ Disallow: /skin/ Disallow: /stats/ Disallow: /STATUS.txt Disallow: /tag/ Disallow: /var/ Disallow: /wishlist/
That should help to reduce waste of server resources and hits on the server, making servers perform better for actual customers. Do you recommend any other magento tips and tricks to improve seo?
