What is SEO?

[WandaCC]

Search engine optimization, or SEO, is the activity to improve search engine rankings.

Example: When you search for cupcake stores online, the search engine uses the words enter to find sites that are most relevant to your query. Some results appear at the top of the list because they contain relevant keywords and headings.
​
These are the parameters that search engines consider. Make sure that your site fulfils as many of these parameters as possible.

I noticed better ranking after I spent some time getting forum backlinks from relevant communities. I joined threads that matched my site's topic and added helpful comments with my link where it made sense. Just make sure the forums allow links and you're not spamming—keeping it natural worked for me. It also helped bring in a bit of traffic from people reading those discussions.
