There are a good deal of different steps involved in properly optimizing a website. On site factors and changes, the time it takes to build a proper backlink profile, and making sure your website is properly built is a weighty deciding factor with the search engines.
On page, on site optimization is a time intensive project. Your content needs to be broken down, weighed and evaluated against your competitors as well as against the search engine guidelines. Your entire website needs to be taken down to its base components, the text, images and navigation all need to be optimized to ensure you have the best chance to rank your site. Some of the larger concerns you have with your on site work are avoiding being spammy with your content, avoiding using any tricky pieces of code to hide text or images – even if these are done by accident they have very real consequences for your website. Avoiding on site optimization issues are basic affairs however, and you can use your gut for the most part to avoid them.
All of the on page work that is done, and for all of the time that it takes to do properly, the off site optimization is just as intensive. There is no real handbook on how to properly perform off site optimization, but there are a couple of key points you can keep an eye on. While you have no real control over who, or what links to your website initially, you do have the ability to manage those back links pointing to your website via Google Webmaster tools. There is thankfully some reprieve where your back link profile is concerned, as the search engines are pretty good at picking out which websites aren’t on the up and up. One of the largest concerns that website owners seem to get worked up about are having links from websites that are obviously selling links to anyone that will pay. Well thankfully, the short story is that it’s highly likely that Google knows they’re not playing by the rules and any links that may be pointing at your site won’t be a problem for you. Matt Cutts, Google’s head of spam gave a brief answer to this concern, the main points to keep in mind:
Websites that sell links will see their toolbar PageRank downgraded by 30, 40 or 50%.
The site will no longer continue to be able to pass PageRank.
Sites they link to will no longer benefit from those links.
