my articles url structure looks like this one : http://www.kol7aga.com/egypt-team/1755-abu-trika-angola.html where : egypt-team = the category name 1755-abu-trika-angola.html= article title manually translated to english. i decided to change the article url to include my title keywords in the same language(arabic) so the url will looks like this one: http://www.kol7aga.com/akhbar/1763-إقتراب-ظهور-العملة-الخليجية-الموحدة.html which looks like this in the address bar where it unicoded so search engines can read it in arabic my question is : is this suppose to perform better since im mentioning my keywords in url ? my second question is : a friend told me that the spiders cant recognize this so it give 404 through google webmaster tools is this true ?
If you think most people will be searching for your site's content in English then having English URLs is the best way to go IMO.
they are searching in arabic thats why i thought about using the arabic in the url but as i said im afraid of not getting indexed by google since the 404 is showing to my friend in his webmaster tools
Why don't you try it with one new page on your site? Add a page to your site w/ an Arabic URL... build a few links to it, and see if it gets indexed or if it shows up in YOUR Google Webmaster tools as a 404. I wouldn't blindly take peoples word for things. Your friend might have done something slightly differently than you and received drastically different results. Almost anything you want to know about SEO you can figure out yourself by setting up controlled experiments.
agreed my articles i just added to my website has been indexed by google so i guess i will wait until tomorrow to see my webmaster tools and if it gets 404 or not .
