The most important part of SEO is making sure your site has unique and fresh content. If the content on your site does not appear elsewhere on the web, the search engines will weigh it more highly than copied content. On the same token, newer content is weighted more highly than aging content.
With SEO, don't be afraid to make mistakes. If you try something and it doesn't work, you can always come back later and make changes. One of the most important things is to keep putting out new content and keep your pages fresh, so even mistakes will have a positive impact on your search engine rankings, as long as you take care of errors as soon as you notice them.
When setting up your site for SEO in English, make use of synonyms for your target keyword. Search engines in English are generally smart enough to recognize synonyms and will place more weight on your page if you have more instances of the keyword, while you avoid the detracting effect of keyword stuffing.
To get a gauge on if your SEO is working, you have to monitor your standings. Monitor with a tool such as Google taskbar to best keep an eye on your page rank. You'll also want to have an idea of where your site visitors are coming from and which key words they're typing in to find you.
If you are going to spend money at all in your SEO efforts, a wise buy would be to open a PPC account. A pay-per-click campaign with Google or any other competitor will help you get your site ranked highly in a hurry. There's nothing these big companies behind search engines love more than money, so it's a "shortcut" for the people who can afford it.
Purchasing SEO software might sound like a good buy, but you should always avoid these types of automated systems. If you are not knowledge enough to construct your own campaign and you feel that you must spend money, do so by outsourcing your SEO work to a real person or company. Your business is too important to leave in the hands of software.
Give each photo you add to your pages a unique and relevant name. If you do not, then you are throwing away a huge opportunity for SEO. Search engines crawl images and if they see further proof of the page's validity it will help with the page rank. Be sure to fill in alt tags also.
