The debate between absolute links and relative links continues to live on in the SEO world. The individual significance of each has been contested, but it is widely regarded that absolute links provide better SEO value on the whole than relative links.
Many believe that absolute links have less potential for getting messed up when search engines index your page. It shouldn’t really make a difference, but many conclude that this is reason enough.
Furthermore, content scrapers and RSS services may ‘repurpose’ your content legitimately (or not). In either case, shouldn’t a proper back-link be attributed to your site? This situation favours absolute links. Although this is a minor argument, it’s still worth considering.
When assessing page structure and layout, there is a subtle, yet strategic way to use images in an SEO-friendly manner (beyond ALT tags) that improves your search rank while allowing you to integrate the necessary marketing message(s). Confused? Let’s look at an example:
Suppose you operate a travel site and you want to optimize a given page for the term “Las Vegas hotel”. Suppose that you also want to include an enticing marketing message such as “Book now and save 20%!”. The aforementioned tagline lacks descriptive text, but possesses persuasive characteristics. That being said, you may want to place the tagline in an image and the key phrase (i.e. Las Vegas hotel) in a header tag. This places emphasis on the desired term, yet still provides a marketing opportunity without compromising keyword consistency.
In other words, images are a great place to insert marketing messages that lack the necessary keywords and phrases. Leveraging this technique will ensure that descriptive text is indexed, while less marketing jargon is overlooked. The combination of keyword-rich content and enticing messaging will satisfy both sides of the strategic equation.
