Why SEO Tools?

According to studies, over 80 percent of internet users use search engines to find information, services or products. Of these again around 80 per cent only look at the results of the first page, 70 per cent of that only the first three results. The best internet site hence is useless if it is not listed in the top of search results. Exactly that is achieved with SEO (search engine optimisation). To improve your ranking on Google, we recommend these 100% free SEO tools.

First: a little bit further Information about SEO. SEO is differentiated between OnPage and OffPage optimisation. Certain keywords, for instance, belong to OnPage optimisation aiming to complement the search words on potential customer: It can hardly be expected that someone looking for information for an SEO agency would type in the word “printing cartridge” on Google. Besides that the foundation and structure are important, also loading times mustn’t be neglected – nobody likes to wait five minutes to get displayed the desired contents finally. A part of OffPage optimisation is the so called linkbuilding. The more links exist to an internet page the more this is valued by Google. However, quality is crucial here and not quantity.

Afterwards you could solve the problems yourself, or the seo-nerd supports you with a sustainable search engine optimisation. A first analysis you can conduct yourself first, however, for this numerous free SEO tools are available on the net.
