| black hat seo | Aggressive SEO strategies with the intention of manipulating search engines. Tactics against webmaster guidelines that can cause a site to receive a penalty or be banned from search results. |

| critical rendering path | The sequence of steps a browser goes through to convert HTML, CSS and JavaScript into a viewable web page. |
| code swapping | Code swapping is similar to cloaking and aims at changing the content in a site after high ranking has been achieved for that site. Basically, the optimised page is switched with another, different from the original one in terms of content. Yet, on a re-index, the content that has been changed will be detected and another ranking algorithm will be applied. The use of this technique might lead to Google penalization. |
