It's quite easy to get carried away when using SEO strategies to try and get your website pages to rank well in Google and other search engines. Often these tactics are used excessively or inappropriately. The aim is to get quick wins in terms of getting a website up to page one of Google and ideally into the coveted top three spot where the most traffic is.
Sadly the excessive use of certain tactics may cause the opposite effect, not only affecting the rankings negatively but also causing a poor user experience when someone browses your site.
Some website owners, especially beginners, get overly enthusiastic about optimisation because they lack experience or haven't learned from a reputable source. In their attempts to impress search engines, beginners in SEO techniques might not even realise when they are overdoing it until they see the rankings crumble away.
On the other hand, some more experienced webmasters deliberately use certain tactics to try and trick search engine algorithms in their attempts to boost their website's rankings. This may even work in the short term but in the long term, search engines have a habit of closing loopholes and what worked last month may not work this month or in the future. All webmasters hope for quick ranking progress but some tactics can have the opposite effect and cause Google to penalise your site.
