What are the new algorithms, and what do they do?

Google has implemented, and is persistently updating, search results ranking algorithms, which aim at lowering the rank of “low-quality sites” and return higher-quality sites near the top of the search results. Google Panda, Google Penguin and Google EMD are examples of effective algorithms which significantly reduce “spammy” backlinks.

Google Panda

Google Panda, the latest Google’s search algorithm, aims to promote the high quality content site by dooming the rank of low quality content sites. In other words, its main objectives are to lower the rank of "low-quality sites” and return higher-quality sites near the top of the search results.

However, since its release and updates, many sites have revealed terrible aftermaths of this algorithm. As Google Panda is predominately a content quality filter, if you webpage consists of a high quantity of low quality backlink, not only will your website will be penalised, but your rankings will plummet dramatically.

To avoid detrimental damage and an infamous reputation, there are five strategies you can undertake in order to avoid this destruction:

1. Separate Out Low Quality Content

2. Focus On Unique Content

3. Concentrate on Clout & Authority

4. Keep Advertising Ratio Healthy

5. Recognise & Track Panda Updates

Google Penguin

Google penguin is another algorithm site which is aimed at reducing search engine rankings of websites that infringe Google’s Webmaster Guidelines by using black-hat SEO techniques, such as keyword stuffing, cloaking participating in link schemes deliberate creation of duplicate content, and others. Google penguin has the power to flag your site if backlinks are incorporating irrelevant outgoing links into a page of content.

Says Google, Sites affected by this change might not be easily recognisable as spamming without deep analysis or expertise, but the common thread is that these sites are doing much more than white hat SEO; we believe they are engaging in webspam tactics to manipulate search engine rankings.

On April 24th 2012, Google released the biggest change to its search engine algorithm in over 8 years – the “Google Penguin” update. The renovated search engine algorithm began penalising websites that obtained poor quality links, and websites that had too many “SEO Optimised” anchor text links. For the first time ever, links can poison your site, negatively impacting your rankings. Because links are very difficult to remove once they’ve been built, Penguin makes it almost impossible for websites to recover from link-based penalties.


Google EMD (Exact Match Domain)

Google EMD is another algorithm, and as the name depicts, EMD never refers to sites with search terms in their domain name, in turn makes these sites rank high. EMD targets on domains with deprived content and accurately match the search terms they hope to be searched for. For example, online-pet-accessories-shop.com. Just a generic search term this domain contains, with no brand recognition and quality content available. Such domains contain no content and if present, copied from other websites.

Danny Sullivan quotes, “EMD seems targeted after low-quality sites that are “in between” these two things, perhaps sites that have content that doesn’t appear scraped because it has been “spun” using software to rewrite the material automatically.” He says, Google never targeted Cars.com for “cars”, Usedcars.com for “used cars”, Cheaptickets.com for “cheap tickets”, Movies.com for “movies”, Skylightbooks.com for “books” etc.

In short EMD’s are targeted, only those with poor content.
