I say the magic of google, because lets face it, it seems like completer sorcery from the outside. The reality is that search engines are nothing more than a computer program which is designed to help us navigate the ever-growing amount of information on the internet. There are other search engines out there of course, but google is the go to guy, at least in my experience. Bing, Yahoo! and Baidu (china's #1 search engine) enjoy a share of the market, but google is the top dog.We all use search engines so much, and the term 'google it' is used as part of everyday language these days, which gives search engines (especially google) a load of power. They're our gateway to the world, without them we wouldn't be able to index and find half of the information we search for.Using a search engine is like hitting the library and getting the librarian to help you find stuff. We've come to trust search engine results so much that very few of us actually question the source from which the data is actually pulled. We rely on google doing the research for us and expect that they've provided us with what we were after.We've come to expect that they'll match our search, our
keywords with the right page or pages for us, but how do they do it?Art ot Science?Search engines are not people who go and look at each site weighing up each one and considering it's design, carefully reading it's content and engaging with it. They are a series of elaborate programs which while they mimic human behaviour to an extent, they acre actually studying the websites codeTo most of us this code looks like a load of nonsense, but search engines can quickly and effectively interpret this data and use it to understand exactly what the website is about. The code tells these programs what to everything they need to know, like the difference between bold and italic text or what's a heading and what's the body of text.They know which buttons you can click and what pages are linked to one and other. The one thing they can't do (not yet anyway) is understand and read images like we can. This is why "alt text" is so important, as it's what the programs read and decipher to understand what the image is about.Searching to ResultsGoogle are constantly updating and improving their complex algorithms, meaning that the goalposts keep moving effectively. But these algorithms perform three major tasks - they crawl, index and retrieve the data,CrawlingGoogle and the others send out computer programs known as "spiders" or "bots" which scan billions and billions of web pages and note their information. The links in these sites lead the bots to more pages and more information. This process will never truly end because websites are always being added to the fray, and they also revisit previous sites to check for updates, amendments, new content and links.IndexingOnce these bots have crawled the internet and gathered the information they need to index it. To do this they store it in databases that hold billions of web pages that they are monitoring online. The index is stored in huge data centres where their robots can easily and quickly access the information to update it or search it for answers when there's a search conducted.RetrievingThis final step is the one that we all are familiar with, this is the part where the search engine mines it's database for the information we're after and delivers it to us on a SERP. These are ranked in order of relevance, and they do it in less than 1 second, which is mind blowing when you think about it. So when your do a search on google, they're not actually searching the entire internet, they're instead searching their own indexed library of sites. By having great SEO, you can help Google’s bots know when your website is a relevant result for a search. One google query uses 1,000 computers in 0.2 seconds to retrieve an answer. But no one knows exactly how search engines choose which websites to pick from their database to show on a SERP. The mystical algorithm is intentionally kept a secret to stop people hijacking it and making the market unfair.If google released then it would quickly become the wild west, and search result would start showing the best at playing the algorithm rather than the most relevant result. Despite not knowing the exact details of the search algorithm, we do have a reasonable understanding of what influences our web rankings — that’s what giving your site good
SEO is all about. Understanding RankingsGoogle’s magic algorithm relies on more than 200 parameters to figure out which websites will be most relevant for a particular search. They search their database, looking at how each website matches a search phrase (your keywords) and they also consider the site’s popularity and reputation. Websites rank higher on searches when they're popular, so getting a decent flow of steady traffic is important. SEO experts agree that these following elements play a role in how well your website ranks in searches. These elements form the basis of SEO.DomainThey search to see if the phrase (keywords) are in the website’s domain name.Titles and DescriptionsThey search to see if the phrase is found in the website’s page titles or descriptions.Keyword FrequencyHow frequently the phrase (keywords) are found in the website image and alt text.Fresh ContentHow regular and recently the website was updated.BacklinksHow many other websites have links to the site.Link QualityOut of them backlinks, how reputable are the sites? Are they spammy and misleading or professional and helpful?EngagementThe quantity of visitors from SERPs and how long they spend on your site.Bounce RateHow many people immediately leave after clicking on your site? A high bounce rate has a negative affect on your website's rank.Brand ReputationHow often the brand, business or domain is mentioned in news and media.Social MediaHow often people mention your site in Tweets, Google+ and Facebook posts.By using a combination of these factors (and more) google aims will provide the searcher with a list of results that are best suited to the keywords.Links MatterSearch engines don't find every single site on the internet, there are simply too many. The bots do their best to find them all but they mainly find sites by following links, if you have no links then the bots will have a harder time finding it. To make sure your website doesn't get overlooked, the best thing you can do is submit your sitemap to google directly. Then you can work on getting links from other reputable websites. These backlinks will help make sure you avoid creating a website that google never finds.
