Ranking in google & other Search Engines

Below I have noted some simple checlists for ensuring a page is open to search engines and is optimised for Search Engines

1) Ensure that the Meta tags are filled in and that you comply with what the tag is used for.
2) Try to target no more than 3 keywords per page.
3) Ensure you use the header tags.
4) It's a good idea to include targeted keywords in title tag, keyword tag, header tag and content.
5) If you are linking from one page to another page in your site ensure the anchor text is decriptive.
6) Same with backlinks and ensure that the source site has relevence.
