Hello
You have asked for someone who is preferably English - I can confirm that by saying that I am one of few UK Freelancers who actually have a sufficiently high standard of English to pass the UK English Level 2 exam and also Academic Writing exam. I believe my English skills are the highest available on Freelancer when you add an unbeaten 98% for US Level 3 English.
I am very familiar with SEO content and the insertion of keywords so the text still reads as though it is written for humans, not search engines.
I am curious to know exactly what you mean by checking 'meta data' as that has a variety of meanings.
As far as my proofreading skills are concerned, in the first page given, you refer to 'stocks' brokers' rather than 'stockbrokers' and from a typography angle and professional layout, for sectionhead ers you have 'Compare Forex brokers' etc. The 'brokers' in each section should start with a capital 'B' - 'Compare Forex Brokers'. I also note that you have used the European comma to separate number points, like '2,5' to mean two and a half - the UK way is '2.5'. using a full stop between.
A professional website cannot afford to have mistakes, not even tiny ones.
I may not have been with Freelancer as long as some, but my full profile will show I have over 280 5* ratings for writing, editing and proofreading, and I would be delighted to add you to my rapidly expanding list of clients who want the highest level of English available.
Kind Regards
David Dundas
