There is no official certificate that makes someone an SEO expert, which is why this question is so debated. Most people feel ready to use that title when they have helped real websites grow their search traffic, solved problems that were not covered in tutorials, and can explain their decisions clearly to clients or employers. Experience matters more than courses here. If you have run campaigns, tracked results, and learned from failures, that already puts you ahead of most beginners. What do you think should be the real standard for calling yourself an SEO expert?
