These are not complex for you to do and are something that should be fundamental when you create a new site. WordPress is an ideal platform as it typically lends itself well to search engine optimization.
The first step is for you to ensure you have set your title tag correctly. This needs to be 64 characters in length. Any longer and it will be cut off and this will look very odd in the search engine results.
The title tag needs to tell people what your site is about in such a way to entice them in to your web site. It needs to include a keyword that is specific for the page the title tag is on. Every page on your website should have its own unique title tag. You should never use the same title tag on every page.
Next are your meta keywords and meta description. These tell the search engine spiders what your site is about. They are not massively important to the search engines, as most of them will analyse your site to see what it is really about.
These are important if you are using Adsense as without these meta tags in place, you find your Adsense ads are not focused on your niche.
The meta description is important because it appears in the search engine results. It is 150 characters for you to get people to click on your link and come to your website. You need to be concise and enticing in the same sentence.
Your meta keywords and description should also be unique for each page within your site.
Any images on your site have what is known as ALT tags. These are tags which provide an alternative description for the visually impaired. These are noticed by the search engines and can get your images ranking well. Make sure you do not attach the same keyword to too many ALT tags and add the word graphic, picture, image or something similar afterwards. This will again help tell the search engines your website is relevant for those keywords.
On top of this you can include your keyword in the header 1 (h1) tag on your page, i.e. the title in the text. This is another indicator to the search engines that your site is important for that keyword.
Using your keyword well within the text of your page and including related keywords around it will also help your site rank.
You must make sure you do not spam or keyword stuff any of your pages because it is a surefire way to get yourself dropped from the search engine results.
By performing some simple on page SEO optimization you can gain the advantage in the search engines. Remember that not all marketers do this, and this can put you ahead of your competition, which is vital for your profitable success.
