SEO is very important for any website including Arabic websites, while competition is high on english content, you can enjoy the freshness of Arabic Content in some fields and get ranked ahead of other competitors.
If you are making SEO for your Arabic website, here are some tips that I hope will benefit you:
1-Make It an arabic website: Some webmasters think they just need to translate two or three pages from English to Arabic and they can have what called “Arabic Website”. By Arabic Website: I mean this :
-Use the subdirectory /ar in your main domain, for example : www.domain.com/ar/
-Make it all Arabic, Text, Header and every single word in it.
-Use RTL pages and make sure your content is 100% Arabic.
2-Get An Arabic Back-links: Send Arabic PRs to Top Arabic News Websites and Blogs, have some links to your website in it’s Language from local websites.
3-Don’t use An Auto Translation service without a content review from a Native Speaker.
4-Ignore the search results from forums when you are monitoring your keywords rankings. Most Webmaster ger frustrated when they search for a keyword they think they should rank for and find top 5 results coming from local forums, I tell you this: most users ignore these results too, I have worked on many keywords that were ranked #5 in the first search page, and the click through rate for these results was very high, sometimes it reached 40%.
