I have written 34 car parts SEO texts in Polish language, for a web-shop. Average number of 250 words per text. Very demanding task but I proud myself for creativity. Why was it demanding? It is always demanding to write 34 unique articles with very similar keywords and phrases in one batch. However I have already written hundreds of SEO articles with similar keywords and topics over the years. I find it rather fun. Believe me or not, when you approach your work like that, the satisfaction from a well done job is a great bonus!
