When you deal with a business, which is spread out internationally and/or want to exploit markets in different countries, then you will come across this: < rel=”alternate” hreflang=”xx”>. This piece of coding basically shows the spiders, that your pages in another language aren’t duplicate pages, but optimised for users from different regions and in different languages. This will result in people getting to the correct page with their local content.
Hence, use href lang on your language page only if you have similar content, but different pricing/shipping address/ contact information, or if that page is completely translated into another language. It won’t make sense if you implement href lang if each those pages already have unique content.
Although we want our pages to be indexed by Google, this little coding snippet lets the spiders know not to index that page – sounds right about right, doesn’t it? No index is used for pages, which the webmaster doesn’t want any other human to find out about, such as employees only pages or any promotional page, in order to communicate to the segmented customers. This is how the coding looks like: <meta name:”robots” content=”noindex,follow”>
Basically indexing means, that you are trying to make the Google spider understand the content of your website, whereas ranking mostly involves in how to rank your content on the SERP. There are many techniques, in order to improve the indexing, which are mostly technical, such as submitting your sitemap to Google Webmaster Tools and your website URL to search engines. However, improving your rankings requires you to focus on your off- and on-page optimisation, such as link development and optimising meta descriptions and titles.
Using the Google Keyword tool will show you that both forms are searched upon. However, which one should I focus on? It would be a shame to restrict yourself to on or the other, because we tend to use both the plural and singular form of words casually. Hence, don’t optimise just for one keyword phrase – find out which keywords convert and have a good search volume, in order to target visitors to your sites.
