PHP Coding changes in our existing blogging website to make it SEO compatible

I am looking for a PHP developer to make specific coding changes to our existing blogging website in order to make it SEO compatible. The ideal candidate will have experience in complete knowledge about php coding with larger database , optimizing meta tags and keywords, implementing schema markup, and improving page load speed. The deadline for these changes is flexible, but it should be done as soon as possible. SEO optimization is a top priority for our website, so it is very important that the developer has a strong understanding of SEO best practices and can implement them effectively. Relevant Keywords should be applicable, and clearly associated with page body content. First of all the all the keywords should be in Small letters, even if they are insered by mistake in capitals All the Tags inserted in the blog should be converted and displayed in the metatags as key words in the header Keywords should be used as allowed and accepted by the search engines (placement, color, etc.). Each and every blog url should be indexed and added to the index file automatically Keywords should not be utilized too many times on a page (frequency, density, distribution, etc.). They should be used naturally within the page content. Redirection technology (if used) should facilitate and improve the user experience. But this is almost always considered a trick and is a frequent cause for removal from an index. Redirection technology (if used) should always display a page where the body content contains the appropriate keywords (no bait and switch). Redirection technology (if used) may not alter the URL (redirect) or affect the browser BACK button (cause a loop). It also may not display page information that is not the property of the site owner without sound technical justification (e.g., language redirects). Pages should not be submitted to the search engines too frequently. simple cron job should be done to submit the indexed urls to the search engines The tags / meta tags used in the keywords can be used as Alt Tags without displaying in the content mention your main keyword at least once at the top of your page. should avoid “duplicate or near-duplicate versions of your content across your site.” Avoid duplicate content And this rule applies to every piece of content on website, including: Title tags Meta description tags Ecommerce product pages Landing pages Image alt text Category pages
