Title Tags. Just as the title of a book or the name of a person or a business is very important, the title that you give to your web pages is equally important. The title tags are usually underestimated by the web designer. Ask your web designer what title tags are- they should be able to tell you exactly what they are and more importantly, why they are essential to your search engine placement. Re-writing your title tags with relevant keywords in the title will make it much easier for the search engines to find your web page.
The meta description is written to explain, primarily to the search engine spiders, exactly what is on that particular web page. Google often (but not always) uses the meta description to explain the result that is returned to the user in the results of the search being performed. Re-writing the meta descriptions sometimes get a better click through to your site as you can guide the user towards your site by using benefit orientated copy to entice the potential customer through to your site.
The meta keywords file is a file embedded in the code of the website designed to let search engine spiders know exactly what the website and web page is about. Nowadays, the file is of lesser importance as Google amongst other search engine spiders do not even look at it. Other search engine spiders do actually look at the file so it is worth making sure that the file is relevant and correct.
Keyword density. The density of your chosen keywords within a web page is very important. Whilst having a density too low can be a problem, of a bigger concern is “keyword stuffing”, i.e. making the text too full of keywords. Whilst this looks like a good idea, it will definitely backfire on you. Your customers need to be able to make sense of every web page. Sometimes web pages need to be re-written as many times as necessary to make sure that the keyword density is correct, the copy reads properly, and most importantly, your customers end up buying or enquiring as appropriate.
Header tags in a web page are headings or headlines. Header tags like H1, H2 tags, etc. will not only make the website read properly, they will also make the search engines take notice. The same advice is true here as for keyword density, don’t just stuff keywords into header tags for the sake of it, however it is a factor that is important and you should definitely pay attention to this.
Image alt tags are descriptions for images. If you have moused over an image and seen text come up, you have seen the actual use of the alt tag. This can make your website easier to use for visually impaired people as they audibly hear the description if they have the correct software installed. You should not have every image alt tag completed with your keyword phrase, however, judicious use of keyword phrases in your image alt tags can really help your search engine efforts.
