If you are not measuring your sites data there is no way you have a business objective. Why would you not want to know which areas of your site perform best and worst in order to optimize your site.
Make sure you have Google Analytics and Google Webmaster Tools configured to your website, so you are able to analyze your data in detail.
Not allowing your site to be crawled
if you make your content difficult for a search engine crawler to find, Google can’t index it and won’t rank it.
Duplicate content is detrimental to your sites SEO. Having pages with the same content create a number of problems for search engines and its best to avoid this.
Hyperlinks that no longer point at a valid page is a broken link and should be fixed or removed. If you are linking to external sites check the link periodically to make sure the page still exists.
Irrelevant anchor text links
The crawler uses link as indicators of the theme of the page its going to. So if you have “click here” as your link text its a wasted opportunity to help your rankings.
